Holiday food waste is a significant issue. The US Ecology Center estimates a 25% increase in waste delivered to landfills between Thanksgiving and New Year’s. The bump in waste is comprised of food and non-food items. Due to the excess and indulgence associated with holiday meals, food waste from uneaten food amounts to millions of dollars. In 2023, it was estimated that 312 million pounds of food was wasted from just US Thanksgiving meals alone. Other holiday waste includes discarded packaging (including online shopping boxes and envelopes), decorations, wrappings, cards, and disposable paper/plastic/aluminum food containers.

While all of the holiday waste is of concern, the consequences of food waste and ways to prevent it will be the topic of this blog. Food waste contributes negative consequences to the environment and to our expendable food dollar.

When food is wasted, there is more waste than just the food itself. There is waste of the seed, land, water, labor, energy, and transportation required to grow, produce, and deliver food to our tables. Further, there is waste of ingredients, time, and energy expended to prepare the food in the home. When food goes into our landfills, it decays producing greenhouse gas emissions; methane is of particular concern as it is a dangerous gas and contributes to climate change. Further, we live in a time when food costs consume a large portion of our expendable income worsened by inflation and supply chain issues. 10.5 percent of all US households are food insecure or undernourished and could use the food that goes to waste.

Whether it be an environmental, social, or humanitarian issue, every consumer needs to do their part to reduce food waste. As the holidays approach, here are some tips to reduce holiday food waste: 

  • Plan ahead. Plan out the meal. Prevent waste from happening from the get go. Digital tools like Save the Food’s Guest-Imator can help consumers calculate how much food will be needed. 
  • Buy only what is needed. If you knowingly buy more than needed, have a plan for the leftovers.
  • Store food properly if purchased or prepared ahead. Put meat, poultry, seafood, eggs, and produce in the refrigerator as soon as you get home. Potatoes, onions, sweet potatoes, squash, and pumpkin should be stored in a cool dark place. Freeze bakery items to keep them fresh. 
  • Encourage less plate waste by using smaller serving spoons. Send uneaten food left on a plate home with guests in take home containers. Label with name and refrigerate until they depart.
  • Refrigerate leftovers within two hours of cooking or removing food from a warming appliance to prevent foodborne illness. Cool foods quickly using an ice bath or downsizing portions. Avoid crowding foods in the refrigerator; leave space so air can circulate.
  • Share leftovers with guests in take-home containers or donate to an agency in your area that accepts prepared food donations.
  • Be creative with leftovers. Use leftovers to create a new dish–turkey pot pie, casseroles, soup, and stock or broth. Incorporate leftover veggies into omelets. Turn potatoes into pancakes. Cornbread into salad. Charcuterie into pizza. Squash into mac and cheese. Freeze individual meals for later use or quick meals.
  • Use refrigerated leftovers within 3 to 4 days or freeze to extend their use.
  • Freeze leftovers. Allow food to cool completely before putting in the freezer. Even pumpkin pie can be frozen. Frozen leftovers are best used within 2-6 months for best quality but will keep indefinitely in the freezer. Package carefully to prevent freezer burn or dehydration and be sure to label and date the food.
  • Save food scraps like vegetable peels and meat trimmings to make broths; scraps can be gathered and frozen until ready to use for broth. If not saved, compost scraps and leftovers that go bad whenever possible. If you are unable to compost, find someone or a group in your area that does.

This holiday season, think about ways that you can reduce food waste. It is up to each one of us to change our unsustainable consumption and wasteful habits.

Go ‘Bananas’ for Summer Treats

Marlene Geiger

July is National Ice Cream month and has its own day, the 3rd Sunday in July! Ice cream as we know it is made from dairy products, sweeteners, gelatin, flavorings, fruits and other ingredients. America loves ice cream. In fact, the average American consumes nearly 22 pounds of this delectable dessert per year.

But look out ice cream, there’s a new ‘one ingredient ice cream’ in town and it’s taking the internet and media by storm! It’s low in fat, cholesterol, and sodium, and is a great source of dietary fiber, potassium, and manganese. Further, it’s perfect for those looking for a guilt-free, dairy-free, gluten-free, nut-free, soy-free, egg-free, vegan or paleo treat with no added sugar. What is it?

If you guessed BANANAS, you are right! Thanks to a banana’s high pectin content and a bit of kitchen wizardry, bananas make a wonderful soft-serve treat. And because it’s a simple, make-it-yourself treat, you can personalize it with the addition of other fruits, nut butters, chocolate chips, nuts, cocoa, spices, or any other add-in desired. Or, bananas can be the only ingredient.

Ripe bananas

Besides bananas (and any other fruit or add-in desired), you will need a high-powered processor to pulverize the fruit. There are designated frozen dessert soft-serve processors on the market which work very well such as the Yonanas and others. However, a blender or food processor will work equally as well as long as it is powerful enough to pulverize frozen bananas.

So how do you make this magical treat? It starts with the bananas. Always use bananas that are ‘cheetah spotted’ or over ripe. These bananas are the sweetest and have developed their pectin potential. 

Slicing bananas

Peel the bananas and cut into ¼-inch coins if using a food processor or blender; if a designated dessert processor is used, follow the manufacturer’s directions.

Place the banana pieces in an airtight freezer bag and freeze for at least 2 hours before using; 24 hours is best. Do the same with other fruits you intend to use with your bananas. Remove bananas and other fruit from the freezer and let thaw for 10-15 minutes before making your treat.

Bananas and strawberries in blend.

One large banana will make two servings especially if additional fruit is used. The ratio of banana to other fruit is about one banana to 3/8 cup fruit. You can make a bigger batch as long as the food processor or blender is big enough and powerful enough. If using a designated dessert processor, follow the manufacturers’ directions for preparing your soft-serve treat by feeding the fruit through the tube into the pulverizing part of the machine.

If using a blender or food processor, follow these instructions: place the frozen banana pieces (and other frozen fruit , if using) in the blender or food processor and pulse. At first the banana pieces will look crumbled, then mushy and gooey something like oatmeal, and suddenly they will magically become smooth and creamy. You will have to stop occasionally and scrape down the sides and help move the fruit into the blades. After the magic happens, continue to blend for a few more seconds to add a little air and blend in any fruit, nut butters, cocoa, flavorings or spices desired. 

Two bowls of strawberry banana ice cream or frozen dessert.

The banana soft-serve is now ready to eat. Stir in any additional whole or chopped add-ins or top off as desired. OR, put it in an airtight container and freeze until solid or for later use.

Recipe ideas are endless. To get started, check out Banana “Ice Cream”, Banana Ice Cream Surprise or Chocolate Banana Ice Cream.   Or watch the Spend Smart. Eat Smart Banana Ice Cream video.  Let your imagination go!

Asparagus Now and Later

Marlene Geiger 1 Comment

There is no denying it! Spring and asparagus go hand in hand. Whether it comes from the garden, supermarket, or farmer’s market, asparagus is perfect for any meal. While asparagus may be a symbol of spring, it can and should be enjoyed year round.

Bundle of fresh asparagus spears

Asparagus is a great source of fiber, folate, potassium, and vitamins K, E, A, and C. (Because it is a good source of vitamin K, those who are on blood thinning medications should monitor the amount consumed.)  Asparagus does not contain fat or cholesterol and is very low in calories—just 4 calories per spear and approximately 27 calories in a one cup serving.

Peak season is usually mid-April to early/mid-June in the Midwest depending upon the season. When the temperatures warm in June, the spears begin to get spindly indicating it is time to stop harvesting and let the plants mature into their fern-like foliage and replenish for the next growing season.

Selecting and Preparing Asparagus

Green is the most common color of asparagus. However, it can also be white or purple. White asparagus is green asparagus that has been covered to block out light to the green shoots so that photosynthesis cannot take place. White asparagus has a very mild flavor and because of the extra effort to cover and blanch it, it is usually more expensive. Like white asparagus, purple asparagus also has a mild flavor; it also exhibits a nuttiness and sweetness due to a higher natural sugar content. It is best used raw or cooked minimally as it will turn green with cooking. Purple asparagus is a result of a genetic mutation of a variety of green asparagus; purple has 40 chromosomes instead of the natural 20 found in green and contains anthocyanins contributing the purple color.

Regardless of color, select stalks that are smooth, uniform in color, and have compact tips. Avoid stalks that are shriveled, limp, or have open, seedy tips—all signs of aging or improperly cared for spears. Do a sniff test; old asparagus gets smelly fast.

Asparagus can be prepared in any number of ways—broiled, steamed, grilled, roasted, sautéed, air fried—or used fresh or par-cooked/cooled in salads. Whatever cooking method is used, the cooking time is short as asparagus is easily overcooked. Strive for stalks that are tender crisp. 

Wash and remove the woody stems prior to cooking or using fresh. Gently bend the stalk until the woody part snaps away naturally. Peeling is a personal option; some people like to peel the lower stalk or remove the scales when the stalks are ½-inch or larger as the lower stems may be a little tougher.

Storing or Preserving Asparagus to Retain Freshness

Asparagus is best used fresh. Store asparagus spears in the refrigerator with the ends wrapped in a damp paper towel or with the stalk ends in shallow water. Loosely cover with plastic to prevent dehydration. If asparagus has been purchased at the market, cut the stalk ends about an inch before wrapping or placing in shallow water. Asparagus will keep well in the refrigerator for a week or longer using one of these methods. Watch asparagus for signs of spoiling—cloudy water, soft/mushy heads, limp stalks, off odor. If heads are drooping but not soft, remove the head and use the rest of the stalk for soup.

Asparagus can be preserved by freezing, drying, canning or pickling for year-round use. In all cases, young, tender spears should be selected and thoroughly washed. Scales should be removed if the directions/recipe directs such. Blanching is needed prior to freezing or drying. Blanching—scalding vegetables in boiling water or steam for a short time—is a must for almost all vegetables to be frozen. It stops enzyme action which can cause loss of flavor, color and texture; cleanses the surface of dirt and organisms; brightens the color; helps retard loss of vitamins; and makes packing easier. Timing is also critical. Underblanching stimulates the activity of enzymes and is worse than no blanching. Overblanching causes loss of flavor, color, vitamins and minerals.

Freezing. Sort the spears into sizes and cut into even lengths. Water blanch small spears for 2 minutes, medium spears 3 minutes and large spears for 4 minutes. Steam blanching is also an option and takes about 1 1⁄2 times longer than water blanching. After blanching is complete, remove the asparagus from the water and put in ice water. This stops the cooking action and retains color, texture and flavor. After it has cooled, drain and package, leaving no headspace OR tray pack prior to packaging.

Pickling. The addition of vinegar to asparagus increases the acidity allowing for processing in a boiling water bath. The National Center for Home Food Preservation has a tested recipe for Pickled Asparagus.  Note that the use of hot peppers in the recipe is optional. Delicate spears enhanced with garlic and dill remain flavorful and crisp.

Drying (Dehydrating). A dehydrator or an oven may be used. To successfully dry asparagus, follow directions by Colorado State Preserve Smart. Watch the spears closely at the end of the drying period to prevent scorching and be sure to condition prior to long-term storage.

Canning. Asparagus is a low-acid vegetable so a pressure canner must be used to guarantee the spears or pieces are shelf safe and free from clostridium botulinum, the toxin that causes botulism. The National Center for Home Food Preservation provides directions for spears or pieces by hot or raw pack.

Make the asparagus season last as long as possible! Store fresh asparagus properly to retain freshness or preserve it to make the season last through the year.

Spouting or Greening Potatoes . . . Keep or Toss?

Marlene Geiger 4 Comments

“Should a potato with sprouts be used or tossed?” There is a great deal of conflicting advice on the question of use or toss. It comes down to the condition of the potato.

Sprouted potatoes in bag

As the warmer months approach, potatoes in storage may be showing signs of sprouting or even vigorously sprouting; shriveling may also accompany sprouting as the starch in the potato is converted to sugar to feed the new plants. Potatoes have an inherent natural dormancy maintained by endemic plant hormones. The concentration of the hormones in the tubers decreases over time resulting in sprouts forming at the eyes. When sprouting starts to occurs, this is a sign that the dormant period is over and nature is telling them it is time to reproduce. Even under ideal well ventilated, cool, dry, and dark storage conditions, this natural phenomenon occurs. Potatoes that are improperly stored in the home may exhibit the same sprouting and shriveling regardless of time of year as conditions may trick them into “thinking spring.”

Why the Concern?

Potatoes contain two kinds of glycoalkaloids called solanine and chaconine. Both are naturally occurring chemical compounds. Glycoalkaloids are found throughout potato tubers, but are in highest concentration in the leaves, flowers, sprouts, green skin and the area around the potato ‘eyes’. The lowest concentration is found in the flesh of the tuber.

In normal tubers, glycoalkaloids concentrations are small with a slightly higher concentration in a thin layer immediately under the skin and around the eyes. Peeling potatoes and removing the eyes reduces the presence of the compound. The concentration of glycoalkaloids in sprouts is much higher and can be high enough to be toxic to humans. The more potatoes sprout, the greater the presence of glycoalkaloids in both the sprout and potato itself. High concentrations of glycoalkaloid compounds give potatoes an unpleasant, bitter taste and can lead to headaches, vomiting and other digestive issues.

According to articles by Michigan State and North Carolina Extensions, removing the sprouts will allow safe consumption of the rest of the potato as long as the potatoes are firm, not soft or shriveled, and the sprouts are small. Further, most of the nutrients are still intact. But if the sprouts are long (1 inch or more) and the potato has shriveled, it should be tossed.

The same is nearly true for potatoes exhibiting greening. Green skinned potatoes have been exposed to too much light. Light causes the potato to produce chlorophyll and activate the skin cells to produce solanine which has a bitter taste and is an irritant to the digestive system. Because of the bitter taste, most people do not eat enough to get sick. Despite that, always use caution when greening is found on the tubers as this indicates elevated levels of solanine. Peeling the potato and removing the green portions by simply cutting them out will eliminate most of the toxin. However, if more extensive greening occurs into the tuber, throw the tuber away. Never eat tubers that are green beneath the skin. 

Cooking does not destroy glycoalkaloid compounds; therefore, potatoes exhibiting sprouts and shriveling or deep green parts should not used. Potatoes that are firm and exhibiting only small sprouts at the eye and/or skin-deep greening can be eaten if the entire sprout and any green-tinged parts of the potato are cut away.

Storing Potatoes to Prevent Sprouting and Greening

Storing potatoes the right way will prevent sprouting and greening. As mentioned earlier, potatoes should be stored in a cool (45-50 degrees), dark, dry, and well ventilated location for maximum freshness.  Kept in these conditions, potatoes will likely last up to three months or longer. At room temperature, potatoes will usually last about 2 weeks. Storing potatoes in a cellar or cool basement is ideal. Storage areas should always be away from appliances that give off heat or any area that allows light. If potato tubers will be consumed soon, they can be stored in a cupboard/pantry in a paper bag.

Don’t store potatoes in the fridge. Cold temperatures turn the starches in potatoes into sugars. This makes potatoes sweeter and cook dark. Also, potatoes should not be stored with onions. Storing them together shortens their shelf life. Onions produce ethylene gas which causes potatoes to spoil prematurely. The high moisture content of potatoes can cause onions to turn brown and rot.

In conclusion, sprouted or green potatoes are not necessarily destined for the landfill or compost pile.  With certain precautions, the potato may be safe to eat as long as sprouts and green spots can be cut away. If there is extensive sprout growth, shriveling, and deep green within the tuber, potatoes should be tossed to prevent risk of potential toxicity from solanine and chaconine, the two natural glycoalkaloid compounds found in potatoes.

For other questions about food safety and storage advice that will help keep food safe after purchase or harvest, The Food Keeper is an excellent resource. This handy reference tool was produced by the Food Marketing Institute at Cornell University in conjunction with the United States Department of Agriculture (USDA). It contains useful guidelines for storing food safely. The app is just a finger touch away for IOS and Android smartphones users by visiting the App Store or Google Play and searching for “FoodKeeper Mobile App.” The same app is also available for computer or pads at FoodSafety.gov.

Freezing Yeast Dough

Marlene Geiger 4 Comments

The frozen yeast dough products available at the supermarket are a nice convenience. But did you know that yeast dough can also be prepared at home and frozen to nearly duplicate the convenience of a ready-to-use product?

Bread rolls

Fleischmann’s Yeast introduced home bakers to freezing yeast dough in their 1972 publication, Fleischmann’s Bake-it-easy Yeast Book. Included in the book were the very first recipes for frozen dough one could make at home, freeze, and bake later. The recipes introduced were specifically developed for freezing and to this day, they remain the standards for freezing yeast doughs.

It should be noted that freezing dough at home may not yield the same results as commercially frozen dough but is still a means to delicious, freshly baked bread when time is short. Frozen dough manufacturers have access to superior dough stabilizers and freezing equipment that freeze the dough very quickly, allowing doughs to freeze with minimal damage to the yeast and dough structure. Dough freezes slower in home freezers increasing the risk of damage to the yeast and dough structure.

Tips for Preparing Yeast Dough for the Freezer  

  • According to Fleischmann’s Yeast, only yeast dough recipes specially developed for freezing should be used for best results. Freezer dough recipes usually call for more yeast and sugar and less salt and fat. The most success is achieved with roll or pizza dough. The method of preparation is not limited; dough can be made by hand mixing and kneading, mixer, food processor, or bread machine.
  • Original freezer-dough recipes used all-purpose flour. Today, it is recommended to replace all-purpose flour with bread flour as it helps to maintain better structure.   
  • Active dry yeast should be used instead of fast-acting yeast. Fast-acting yeast is not ideal for recipes that require a long rising time. King Arthur Baking suggests making the dough with cool, not lukewarm liquid (water or milk) to keep the yeast as dormant as possible so that it is less vulnerable to damage during the freezing process.
  • To compensate for the yeast that will inevitably die in the freezing process, King Arthur Baking suggests increasing the yeast by ¼ to ½ teaspoon per 3 cups (360 grams) of flour.
  • Dough may be frozen at two junctures:
    1) after kneading and before the first rise (proofing) OR
    2) after the first or second rise.  
    American Test Kitchen tested both junctures and found “freezing the dough between the first and second proofs was the best strategy. The first proof ensured that enough yeast had fermented for the dough to develop complex flavors and for some gluten development for better baked size. The remaining viable yeast cells then finished the job as the dough thawed and proofed for the second time.” 
  • Form the dough into balls for rolls or flatten the dough into a disk about 1 inch thick for pizza crust or dough to be shaped later. French bread, loaves of bread, braids, and cinnamon rolls can be shaped prior to freezing; loaves should be frozen in greased loaf pans and cinnamon roll slices placed on their sides on a lined baking sheet. Tightly wrap the dough with plastic wrap.
  • Flash freeze the dough in the freezer for 1-2 hours. Dough should be covered during flash freezing, thawing, and rising prior to baking to prevent the dough from developing a dry crust.
  • When the dough pieces have formed a hard shell around the outside, transfer to a zipper freezer bag or air-tight freezer container. Return the dough to the freezer. Dough may be frozen up to 1 month. For best results, use dough sooner rather than later.

When ready to use, remove needed dough balls, loaves, rolls, or disks from the freezer and allow to thaw covered in the refrigerator, a warm location, or combination until doubled in size. Do not over proof.  Since the yeast and bread structure have been compromised during freezing, over proofing may cause the dough to collapse on itself.

Previously formed dough can be thawed in a greased baking pan until double. Disks should be allowed to thaw and then rolled or shaped (pizza crust or any shape or specialty desired), placed in a greased baking dish, and allowed to rise until doubled. (Rolled dough for pizza crust does not need time to double unless desired.) When dough has reached the desired size, bake as directed.

Thawing and rising times vary according to the temperature of the dough, the size of the dough pieces, and where thawing takes place. Use these times as a guideline for thawing:
Refrigerator: 8-16 hours
Countertop: 4-9 hours
Warm location: 2-4 hours
Dough balls for dinner rolls take about 1½ -2 hours to thaw and double before baking in a warm location. Loaves of bread may take 4-6 hours at room temperature.

Cinnamon rolls

Recipes for freezer dough can be found on the Fleischmann’s website. Some examples include: pizza dough, bread dough, and dinner rolls. If one is lucky enough to have a copy of Fleischmann’s Bake-it-easy Yeast Book, 1972, a variety of yeast doughs developed for freezing can be found therein.

Fresh-baked bread is always more delicious than reheated. If you plan ahead, you can freeze yeast dough to save time provided you remember to pull it from the freezer early enough—that’s the hardest part!

March is National Frozen Food Month!

Marlene Geiger 2 Comments
March - Frozen Food Month

Some of America’s favorite, most versatile foods are found in the frozen food aisle. There are some 3,700 frozen food options available to consumers catering to every lifestyle, ethnic cuisine, daily food need, or food occasion.

Frozen foods have definitely made our lives easier and offer great value. With a wide assortment of choices from ready-to-cook meals to ingredients and produce that leave nothing to waste, there are so many reasons to prepare meals using frozen foods. Freezing keeps our foods safe and fresh tasting. Here are some frozen food facts from the National Frozen & Refrigerated Foods Association:

  • Frozen foods are picked at the peak of ripeness and flash frozen, sometimes right in the field, locking in all of the beneficial nutrients and keeping them in their perfect, just-picked state.
  • Frozen fruits and vegetables are equally as nutritious as their fresh and canned counterparts.
  • Freezing acts as a natural preservative, so many of your favorite frozen foods contain no preservatives.
  • Frozen foods are consistently priced year-round. You are paying for 100% edible food – no stalks, seeds or rinds. And many frozen foods are perfectly portioned so there’s no waste.
  • Frozen foods last much longer than their fresh counterparts. You can use just what you need and put the rest back in the freezer for next time – wasting less food and saving you money.

We can also freeze many things ourselves at home—summer produce, meat, poultry, fish, eggs, milk, cheese, leftovers, make-ahead-meals, casseroles, breads, cakes, pies, and more. Our food dollars are saved when we use frozen foods in our meals. Prior to freezing, best practices must be followed for any food to retain best quality and be safe after thawing. Check out Storing Food in the Freezer for helpful and safe preparation tips and Freezing Convenience Foods for using your freezer to help with meal preparations.

Although frozen food is convenient, foods in the freezer only remain safe and at best quality if the freezer temperature is at or below 0 degrees F. Keeping a thermometer in the freezer is helpful for monitoring the temperature. The thermometer should be checked frequently to be sure the freezer is maintaining the appropriate temperature. Further, always date and label foods placed in the freezer. Older foods should be used before newer ones for best quality and to avoid freezer burn. Food Safety.gov has a Cold Food Storage Chart for maintaining frozen food best quality; frozen foods stored continuously at 0°F (-18°C) or below can be kept indefinitely.

Elevation? Does It Matter?

Marlene Geiger 1 Comment

While residents of most midwestern states usually don’t think about their elevation, elevation affects all aspects of food preparation–cooking, baking, canning, jams and jellies, and candy making. As elevation rises, air pressure falls and water boils at lower temperatures making recipe adjustments necessary.

Elevation and Everyday Cooking and Baking

When it comes to everyday cooking and baking, there are few noticeable effects of elevation until one reaches 3,000 feet. Higher elevations present several challenges when preparing some foods. At higher elevations, leavened products using yeast, baking powder/soda, egg whites, or steam rise more rapidly, may collapse, and may not be fully cooked. Because water boils at a lower temperature at higher elevations, foods that are prepared by boiling or simmering will cook at a lower temperature, and it will take longer. High elevation areas are also prone to low humidity, which can cause the moisture in foods to evaporate more quickly during cooking. At elevations above 3,000 feet, preparation of food may require changes in time, temperature or recipe.  For those that find themselves at higher elevations, Colorado State University and New Mexico State University have excellent tips and guidelines for successful baking and cooking.

Elevation and Canning Safety

Because water boils at 212°F at sea level and decreases about 1°F for each 500-ft increase in elevation, adjustments must be made when canning foods at home to ensure home-canned foods are processed safely. The amount of time that jars are held at a certain temperature during canning is important to producing a safe product. Processing times for most recipes are based on elevations of 0-1,000 feet unless stated otherwise. When elevations are above 1,000 feet, extra time is added for food processed in a water-bath canner. For food processed in a pressure canner, extra pressure is added. Both adjustments are needed to get to their respective safe processing temperatures for high acid and low acid foods. 

USDA and National Center For Home Food Preservation (NCHFP) recipes include a table for proper processing based on elevation to insure sufficient time and temperature have been reached for a safe, shelf-stable product. In the NCHFP table for Crushed Tomatoes, note that time is increased in 5 minute increments as elevation increases for boiling water canning and pounds of pressure is increased for pressure canning. (Crushed tomatoes are one example of a food that can be processed by either boiling-water bath or pressure.)

While time is adjusted for water-bath canning, pressure regulation differs by the type of pressure canning equipment used—dial- or weighted-gauge canner.

Elevation and Sugar Concentrations

Elevation is also a factor in candy making and the gelling of jams and jellies when pectin is not used. At higher altitudes, atmospheric pressure is less so water boils at lower temperatures and evaporates more quickly. Syrups become concentrated and reach the gel point at a lower temperature. The concentration of sugar required to form a gel is in the range of 60 to 65 percent which occurs at 217 and 220 degrees F, respectively, at sea level. As elevation increases, the gelling point decreases by 2 degrees per 1,000 feet. When elevation is not taken into consideration, overcooked jam is the result as too much water has boiled away leaving a sugar concentration that is too high, leaving a jam that is gummy, dark in color or tough. The same is true for candy making. For each 1,000 feet above sea level, reduce the temperature in the recipe by 2 degrees F to prevent overcooking. Colorado State University provides a High Elevation Candy Making (Sugar Solution) Adjustment chart for various kinds of candy mixtures.

Find and Know Your Elevation

Elevation matters in all aspects of food preparation. It is especially important for the safety of home canned products beginning at elevations above 1,000 feet. Before beginning the canning process or making sugar concentrations, find your elevation using one of these sources to insure proper processing of canned products and prevent overcooking of jams and candies:

  1. Visit a web page about your town or city.
  2. Use an online tool such as What is my elevation?
  3. Use a smartphone app such as My Elevation.
  4. Refer to an elevation map for your state showing approximate elevations such as this one by Iowa State University Extension and Outreach from the Preserve the Taste of Summer series.

Making Granola Bars a Healthy Treat

Marlene Geiger 1 Comment
granola bar

Crunchy, chewy, chocolatey, fruity granola bars are an American favorite breakfast staple and snack. In fact, granola bars are so popular they even have their own annual day of celebration in January. Often considered a healthy food (and they can be), the nutrition label may tell otherwise; most are little more than candy bars in disguise loaded with sugar and high fructose corn syrup, unhealthy fats, and short on fiber and protein. The satiety value is low—in a short time, hunger sets in again.

How can you enjoy your favorite snack without leaving you hungry or wanting more? Here are a couple of ideas to up the granola bar game:

  1. Look for a better bar. Check the ingredients and nutrition label. The ingredients are listed by weight, so the foods at the beginning of the list are the most prevalent in the recipe. Specifically, look for bars that include whole grains (oats) rather than enriched refined grains. Also, look for bars high in fiber (3-5 grams) and protein (5 grams), sweetened with fruit, honey, or natural syrups, and including nut butters, nuts, grains, seeds, and fruits to ensure the best nutrition possible. Granola bars are intended to be a snack, not a dessert, so pay specific attention to the amount and kind of added sugars. Lastly, avoid granola bars with hydrogenated oils and those where most of the total fat is saturated fat.
  2. Make or concoct your own. Homemade variations offer the option to choose healthier ingredients, use more whole grains and less sugar, and control the type of fats and add-ins. The cost is usually less than the store-bought versions. There are an abundance of recipes to choose from. Groovy Granola Bars, lpi.oregonstate.edu/sites/lpi.oregonstate.edu/files/pdf/hyp/groovy-granola-bars.pdf, from Oregon State University is an easy recipe to get you started. It is packed with fiber and protein and provides half of your daily value of Omega-3’s. Change it up with other dried fruits, nuts, seeds, and even a few dark chocolate chips.

Granola bars can be a healthy food. Check the ingredient list and nutrition information on the label to ensure they are a good source of fiber and protein, OR find a recipe that provides nutrition rather than just a sweet treat. Making your own granola gives you complete control over the ingredients to create something healthy and personally enjoyable!

How Ingredients Effect “How the Cookie Crumbles”

Marlene Geiger 6 Comments

Cookies are a favorite treat and especially so during the holidays.  Holiday cookie baking is a tradition for many families and a fun way to honor family heritage.  Whether making sugar cookies for Christmas, rugelach for Hanukkah, or benne/sesame cookies for Kwanzaa, the ingredients play a role in how “the cookie crumbles.”

Cookie baking is more chemistry than art and the ingredients used play an important role in the appearance, taste, texture, color, and flatness of the cookie. Here’s a look at the five traditional ingredients—sugar, fat, flour, leavening agents, and binding agents—used in cookie baking and the role they play.

SUGAR
Besides sweetening and tenderizing cookies, the type and amount of sugar plays a role in the flavor, texture, color, and spread of the cookie. Sugars give color to cookies as the sugar granules melt together caramelizing the bottom and edges and gradually spreading over the cookie. Sugar is hygroscopic meaning it attracts and absorbs the liquid in the dough, which slows down the development of gluten, a protein in flour that provides strength and elasticity to dough. 

Granulated white sugar contributes to the thinness, crispiness, and lighter color of a cookie. Being neutral in flavor and color, it allows the flavors or colors of other ingredients to come forward. With a neutral pH, interference with gluten development is less, allowing the dough to spread more before it sets during baking. When creamed with a solid fat, white sugar easily aerates the dough for puffier cookies.

Brown sugar contributes more tenderness, flavor, color, and rise to a cookie along with a denser and moister texture. The flavor, color, and moisture of brown sugar comes from the addition of molasses. Due to the molasses, it is slightly acidic. In the presence of baking soda or baking powder, the acid reacts with the sodium bicarbonate (alkaline) to produce carbon dioxide. Being more hygroscopic and acidic than white sugar, brown sugar is able to absorb more moisture and slow gluten development faster so the dough sets more quickly during baking.

Substituting one sugar for the other will not affect the sweetness, but will change the appearance and texture of the cookie.

FATS
Fat contributes flavor, tenderness, chewiness or crunchiness, and browning to cookies. Fat options include butter, margarine, shortening, or oil. When sugar is creamed into a solid fat, air pockets are created in the dough resulting in puffier cookies. Further, fats can inhibit or enhance gluten development. When solid fat coats gluten strands, gluten is inhibited and yields tenderness. Chewy cookies are the result of water in melted fat binding with gluten to strengthen structure.

Butter, in solid form, traps air during creaming which expands with heat producing a fluffier cookie. For best results, butter should be at room temperature for baking. Some recipes may specify the use of melted butter or browned butter; melted butter incorporates no air, leading to denser, flatter, and chewier cookies. When butter is browned, the water in butter evaporates resulting in a very dense, but flavor-rich cookie. (Butter is at least 80 percent fat and 16-18 percent water.)

Unsalted butter is the standard in baking unless otherwise specified. However, the amount of salt in salted butter is so small that it can be substituted for unsalted butter in most cookie recipes.

Margarine, made from vegetable oils, may contain more water and less fat than butter. It functions similarly to butter and produces a similar texture. However, cookies made with margarine may be thinner and spread more during baking. Depending upon the fat/water ratio, margarine may not be a direct substitute for butter; for best results, recipes specifically tested with margarine should be used.

Vegetable shortening is 100 percent hydrogenated vegetable oil, contains no water, and has a higher melting point than butter. Cookies made with shortening tend to rise higher, hold their shape during baking, and have a soft, fluffy texture. Cookies made with shortening may stay soft longer after baking because shortening returns to a semi-solid after baking.

Vegetable oil is 100 percent liquid fat. Cookies made with vegetable oils are denser and flatter as very little air can be incorporated. A neutral flavored vegetable oil should be used to retain the intended flavor of the cookies. 

FLOUR
Wheat flour contains gluten and provides structure by forming a web of gluten strands to catch air bubbles from creaming liquids and leavening agents. Sugar and fats, as mentioned earlier, help restrict gluten formation for a softer, more tender cookie. Generally, all-purpose flour is the flour of choice for cookie baking.

LEAVENTING (RISING) AGENTS
A leavening agent helps cookies rise while baking; the type used affects the texture and structure of cookies. The leavening agents most commonly used in cookies are either baking soda or baking powder.  While they both create rise during baking, they function very differently.

Baking soda (sodium bicarbonate) requires an acidic ingredient such as vinegar, sour cream/milk, brown sugar, lemon juice, or chocolate to release carbon dioxide and leaven the dough. When baking soda and the acidic ingredient combine, there is a single reaction resulting in a denser cookie. Due to the single reaction, baked goods made with baking soda as the only leavening agent should be mixed quickly and baked immediately to get the most rise.

Baking powder is a chemical agent containing sodium bicarbonate and acids giving cookies more rise and a cakier texture. Baking powder is double acting, meaning it provides leavening first when it gets wet and second when it is heated. Because most of the reaction takes place in the second stage, the dough remains stable and does not have to be baked immediately.

It is quite common for both leavening agents to be used in a recipe, but it is a misconception that the two can be used interchangeably.

BINDING AGENT
Binding agents are the liquids in the recipe that hold the cookie dough together, such as eggs and milk which also add flavor, color, structure, moisture, and nutrition. The proteins in eggs, and to a lesser extent in milk, set with heat contributing to the final shape and texture of the cookie. The emulsified fat of the egg yolks contributes to tenderness while egg white contributes to cookie rise.

TIP
While not an ingredient, chilling the dough for 24 hours is one of the easiest ways to improve flavor and outcome. As the dough rests, the large molecules of flour and sugar breakdown and the fat hardens. As a result, cookies expand more slowly, hold their shape, have a richer butterscotch-like flavor, and brown more evenly. 

Each ingredient plays a key role in the recipe. Understanding their role and the contributions each make to a cookie is important to baking the best cookies ever or adjusting the ingredients to achieve the desired cookie. King Arthur Baking has suggestions for adjusting key ingredients to change the texture of a cookie recipe. To get a visual idea of how the various ingredients can affect the taste, texture, and appearance of your cookies, visit: The Ultimate Guide to Chocolate Chip Cookies.

While ingredients are key players, they do not hold all the magical powers; the mixing process and baking temperature also affect the end result. To learn what happens during baking, watch The Chemistry of Cookies.
