My husband and I will be welcoming our second child this August. As excited as we are about our newest addition, we also recognize this will shift our family dynamics and be an adjustment for ourselves and our son, Thomas, who will be 21 months when his brother or sister arrives.
Thomas with his Sweeney grandparents.
In this blog, I am focusing on things my husband and I plan to do prior to baby arriving to help make the adjustment easier (for strategies on how were preparing Thomas for the adjustment, see my previous blog, Preparing for a New Baby: Helping Older Children Adjust).
We are excited that our family is growing, but also recognize our hands will be quite full with two children under two years old. As we close in on the third trimester, I am embracing Benjamin Franklin’s quote: “If you fail to plan, you are planning to fail.” Now, I realize not every detail will be attended to (and there are going to be things I overlook) but having a general game plan and preparing accordingly will help reduce my stress heading into this transition.
Strategies to Help Parents Adjust:
Thomas with Grandma Wall.
Create a plan for who will watch the other child(ren): while we are at hospital Thomas will be staying with my in-laws. We plan for Thomas to do a test run at Grandma and Grandpa’s house overnight before the baby arrives, so he is familiar with sleeping overnight in a new place. Also consider what your child needs with them and make sure to pack those items. For Thomas, this will include his sound machine and sleep sack.
Create a plan for meals ahead of time: caring for a newborn and toddler doesn’t leave a lot of time or energy to prepare meals. There are several different approaches you can take when thinking about advance meal planning. Some may want to organize a Meal Train, where friends, family and neighbors select a date and meal they will be delivering to your home, others may order frozen meals to be delivered. I am planning to set aside a day to prepare several main dish recipes and store them in my freezer for easy meals when the baby arrives.
Preparing nursery and other baby-specific areas: this will look different for everyone depending on the set-up of their home. For me, this will include getting the nursery set-up, washing baby clothes and blankets, creating several diaper changing areas throughout the house, and preparing supplies for nursing. I also plan to set up a subscription for diaper delivery as this will be one less thing to worry about once the baby is here.
Pack hospital bag: this is always nice to have done as we don’t always know when babies will make their appearance. Along with the hospital bag, I’ll also be washing the material in our infant car seat, reassembling, and setting it next to my hospital bag so it is not forgotten!
Ask for help if you feel overwhelmed: babies bring so much joy to our lives, but they are also a lot of work. Make sure to accept help from your partner, relatives, and friends. After Thomas was born my mom stayed with us for several days when we returned from the hospital. It was so nice to have an extra set of hands and we’re planning to have her stay again once this baby arrives!
Make time to care for yourself: After having Thomas, I decided to swim twice a week as preparation for a half-Ironman relay. I really appreciated this time alone to recharge and found I was more patient with both Thomas and my husband after swimming.
Remember to make time for each other: children of couples who have a strong and loving relationship are more likely to adjust well to the new baby. After Thomas was a few months old and we felt comfortable leaving him for a stretch of several hours, we have tried to do a date night (or afternoon) once a month, just the two of us. It isn’t always fancy (sometimes it involves running errands), but it is nice to have that time to reconnect.
Welcoming a second (or third, or fourth, etc.) baby into the family is a big transition for parents but planning and preparing ahead of time can make the transition easier for all involved. With a little preparation beforehand, we are eager to bond as a family.

As spring creeps in, mushroom enthusiasts are just itching to get out into the woods and search for the highly prized morel mushroom. This elusive mushroom is prized for its tastiness and can only be wild-crafted as no one has yet figured out how to grow and farm them.
Besides being prized for their taste, morels are loaded with various nutrients. Because they tend to grow in rich soils, they come packed with vitamins and minerals such as iron, copper, manganese, phosphorus, zinc, vitamin D, folate, niacin, riboflavin, potassium, magnesium, calcium selenium, thiamin, vitamin E, and vitamin B6. However, their nutrient value varies with the soil where the moral grows. Morals are also loaded with antioxidants, help to balance blood sugar and provide protein and fiber. Morals should be eaten within four days of harvest and best within 1-2 days. Due to their sponge-like texture, morels tend to trap dirt, grit, and insects in their gills, so cleaning requires a bit more attention than merely brushing. Illinois Extension says that mushrooms should be soaked in lukewarm salted water for 30 minutes, changing the water a few times. Avoid oversoaking, as it can dilute their flavor. Rinse the mushrooms well and pat dry. Morals can be used in any way that farmed mushrooms would be used. For tips on preparing morals, check out How to Cook Morel Mushrooms–If You’re Lucky Enough to Find Some.
While the wild morel mushroom is highly prized, its’ farmed mushroom cousins—white, shitake, cremini, oyster, maitake–are equally as nutritious and offer delicious and unique flavors. They are also readily available at the supermarket. Even though there are more than 2,000 varieties of edible mushrooms worldwide, most people cook with only one or two. Here is a summary of those most commonly found on produce shelves:
White Button Most common mushroom. Mild flavor, very versatile. Protein-rich.
Cremini/Portobello Baby bella = Cremini; larger, mature form = Portobello. Makes dark sauces and is great for grilling.
Shitake Deep woodsy flavor, especially if dried and rehydrated. Calcium-rich.
Oyster Delicate, mild flavor. Stays firm when cooked; excellent for stir-fry. Iron and antioxidant-rich.
Maitake Also known as hen-of-the-woods. Earthy flavor. Excellent for stirfry. Antioxidant-rich.
The enemy of any mushroom is moisture in its packaging. Fresh morels will keep about a week in the refrigerator, provided they were harvested in good condition. Place them in paper bags and store them in the refrigerator with plenty of air circulating around them. Drying is an excellent storage option, too. A paper bag is also a good way to store purchased mushrooms; this allows them to breathe. Moisture build-up inside the packaging is the fastest way mushrooms break down.
Mushrooms need to be cleaned before use. The best way to clean most fresh mushrooms is to wipe them with a clean, barely damp cloth or paper towel. Washing mushrooms is usually not necessary. If you must rinse them, do it lightly and dry them immediately, gently, with paper towels. Never soak fresh mushrooms in water, which will cause them to become soggy.
Cleaned mushrooms can be wrapped loosely in damp paper towels or a damp clean cotton cloth, placed in a container, and stored in the refrigerator for up to three days; the mushrooms may darken if stored this way.
Mushroom nutrition can be enhanced by placing them in the sun for 30 minutes before use. Since most mushrooms are grown in the dark, they need sunlight to increase their vitamin D content. Exposure to sunlight significantly improves vitamin D. Vitamin D is maximized if the mushrooms are chopped before exposure. Some packaged mushrooms are marketed as vitamin D enhanced.
Dried mushrooms may be an option for those who do not care for fresh mushrooms. Dried or powdered mushrooms pack the same nutritional punch as fresh mushrooms. To add nutrition, the mushroom powder can be included in sauces, homemade bread, casseroles, soups, etc. Several mushroom powder “enhanced” products and foods are now on supermarket shelves.
So whether it is the wild morel mushroom or farmed, store-bought mushrooms, mushrooms are an excellent food for both flavor and nutrition. Take good care of them to maximize both their flavor and nutrition.

It’s artichoke season! Spring artichokes are now available and at their prime! Upon first glance, an artichoke looks intimidating. Artichokes are an ancient food from the plant known as Cynara cardunculus var. scolymus which is a kind of thistle. The part that we see in our stores and eat is actually the flower bud of the plant, also called the head, which has become a highly regarded vegetable. It’s quite intriguing to wonder how ancient man figured out how to eat and enjoy such a thorny-looking thing.

Artichokes are best enjoyed at two different times of the year, spring and fall. The spring season runs from March to May, and the fall season is September and October. 99 percent of our artichokes are grown in California, with Monterey County being the lead producer and the town of Castroville being the “Artichoke Center of the World!”1 Artichokes are also grown commercially in Oregon and Washington. They thrive best in Zones 7-11; however, they can be grown in colder regions, like Iowa, as an annual vegetable.
Artichokes are fiber-rich, low in calories, and come packed with nutrition. Per the Nutrition Valuewebsite2, one medium-sized artichoke cooked without salt (120g) provides 64 calories, 3.5g of protein, 14.4g of carbohydrates, and 0.4g of fat. In addition, artichokes are an excellent source of vitamin C and K, potassium, and antioxidants. (For additional nutrition information, see profile at Nutrition Value.) Artichokes contain the highest levels of antioxidants of any vegetable (polyphenols, flavonoids, anthocyanins, among others) and are loaded with an army of beneficial nutrients that can protect the body from cancer per the National Foundation for Cancer Research3. While a fresh artichoke provides the best nutrition, artichokes are available in other convenient preparations—frozen, canned, and marinated heart.
While nearly all parts of the artichoke are edible, they are prized for their ‘heart,’ which is found at the base of the stem. The parts of the artichoke which are usually inedible include the choke, outer petals, and thorns. The choke, located right above the heart, is stringy and indigestible. The lower part of the petals, which contain part of the heart, are edible by drawing the lower petal through the teeth with the rest of the petal discarded. The thorns are usually snipped off.
When purchasing artichokes, choose those that have a tight leaf formation, a deep green color, and are heavy for their size. In general, the smaller the artichoke, the more tender it will be, and the rounder it is, the larger its heart. Artichokes are best used on the day of purchase but can be stored unwashed in a plastic bag in the refrigerator for up to 4 days. Wash just before cooking.
Artichokes can be prepared by steaming, stuffing, baking, braising, or grilling. Steaming is the most common means of preparation. They are done when the bottom of the stem can be pierced with a knife. Whatever method is used, stainless steel, glass, or enamelware should be used to prevent discoloration and off-flavors. Lemon juice should be used on cut edges to prevent discoloration.
Dani Spies of Clean and Delicious® has an excellent video, Artichoke 101, where she shares how to buy, store, prepare, cook, and eat artichokes. Check this video out, and artichoke intimidation will be over!

With concerns of the high consumption of sugars or need to eliminate sugar from their diet, consumers are seeking alternatives to sugars, high-fructose syrups, processed and artificial sweeteners. While there are a variety of alternatives, perhaps it is time to rediscover an ancient fruit, the mighty DATE, as a sweetener. Besides being a highly sweet fruit, dates provide numerous health benefits, are readily available, available in many forms, versatile, and easily incorporated into recipes as an alternative for granulated sugar or enjoyed on their own or added to food.

Dates are an ancient stone fruit with beginnings in the Middle East dating back to BC days. Dates grow on trees known as date palms (Phoenix Dactylifera) in clusters like bunches of grapes. The big difference is that the date clusters are some 50-85 feet above the ground and require considerable labor to produce and harvest. An article by Food and Nutrition gives a brief description of date production and harvest. While dates continue to be a major crop in the Middle East, they are grown in other regions around the world where conditions are right for them. In the US, dates are grown in California, Arizona, and Florida with the largest production in California’s Coachella Valley, northeast of San Diego. Here, 95 percent of US dates are grown due to ideal conditions: high temperatures, low humidity, and an abundant supply of underground water for their love of wet feet. 1
There are hundreds of date varieties grown around the world. Twelve varieties are found in the US with the two most common being the Medjool and Deglet Noor varieties. Dates are classified as soft, semidry, or dry. Dates have a sweet, caramel-honey like flavor. Fresh picked, they are sweet and succulent becoming sweeter and chewier as they dry. Each variety has its own flavor profile.
Dates are packed with minerals, vitamins and dietary fiber (soluble and insoluble). One date (8g) provides 23 calories, 0.2g of protein, 6g of carbohydrates, and 0g of fat. Dates are a rich source of potassium, magnesium, manganese, iron, copper, B Vitamins, Vitamin K and zinc. In addition, dates provide a high amount of antioxidants in the form of polyphenols, flavonoids, and carotenoids. Despite their sweetness, dates are considered a low glycemic food and do not spike blood sugar levels. All of this ‘goodness’ makes them effective at relieving constipation, lowering the risk of chronic disease, lowering LDL cholesterol, improving brain function, boosting bone health, and improving our immune system along with other benefits still being studied.
Dates are an excellent sugar substitute. In addition to naturally sweetening food, one gets the added benefits of natural fiber and dense nutrients. Beyond the whole fruit itself, dates come in other forms or products: date molasses, syrup, vinegar, sugar (crystals and powder) and paste. University of Wyoming Extension suggests using these products in the following ways: “Date molasses or syrup tastes like molasses but with a less bitter edge. Use it as a liquid sweetener. Date vinegar, fermented from dates, is dark and fruity and an excellent substitute for balsamic vinegar. Date sugar, date powder, and date crystals are dehydrated ground dates. Use them in baking to replace white or brown sugar. Date paste is a smooth puree of pitted dates. It can replace butter, sugar, or eggs, depending on how it is used.”
Despite its name, date sugar is not really sugar. Date sugar is simply ground dried dates containing all the fruit’s nutrients — vitamins, minerals, antioxidants, and fiber—resulting in a product that is granular but somewhat fibrous. However, the intensely sweet granules do look a lot like brown sugar made from sugar cane or beet. It can be used to replace white or brown sugar 1:1 in many recipes for baked good but some experimentation may be necessary to adjust for sweetness or flavor. Date sugar granules can also be used to sprinkle on cereal, fruit, yogurt, etc., but may not be desirable for liquid beverages as it does not dissolve well; date sugar powder is a better choice for these uses.
Since date sugar is different from sugars made from sugar cane or beet, it is no surprise that it creates a product slightly different than something made with sugar in baking and cooking. There are numerous websites that share tips and recipes for using date sugar in cooking and baking including how to make your own date sugar and paste. It may be necessary to increase liquid or decrease dry ingredients as date sugar is hydroscopic and absorbs moisture. Date sugar burns easily so lower temperatures may also be needed. For more specific tips and recipes, visit the PurDate website. Date sugar should not be used for canning. Presently, there are no tested, safe recipes for using date sugar in canning fruit or jams/jellies.2
Date sugar should be stored in an airtight container. Being naturally hygroscopic, date sugar readily absorbs moisture and tends to clump together and may even form a solid brick. For this reason, some manufacturers mix other ingredients with the ground dates to prevent clumping. Bob’s Red Mill uses a small amount of oat flour. If date sugar does harden, Bob’s Red Mill suggests placing the date sugar in the microwave for a few seconds until it begins to soften. Because date sugar is dried fruit, watch it for spoilage as it does not have an indefinite shelf life like sugar.
In summary, date sugar is a nutrient-dense sweetener containing beneficial fiber, minerals and antioxidants making it one of the healthiest sweeteners or sugar substitutes on the market. It is not a highly processed, empty calorie food so it may be perfect for those who are diabetic or are trying to reduce refined sugar intake, add healthy nutrients to their recipes, or eat more natural foods. However, date sugar packs a significant punch of simple carbohydrates and calories, so use it with caution as you would with sugar or other sweeteners. _________________________________________________ Sources (accessed 9 February 2022):

As the days get warmer and the ground thaws, it is time to dig spring-dug parsnips. Characterized by some as ‘the cream of the crop’, spring parsnips come from seeds sown in the spring of the previous year, grown during the summer, allowed to die back in the fall and freeze in the ground over the winter.
Parsnips.
Parsnips can also be dug in the fall after a frost or two, but those left over the winter are sweeter and more flavorful. The extreme cold converts the starches into sugar and allows the flavor to mellow. The timing is critical for spring-dug parsnips; they need to be dug as soon as you can get into the ground with a shovel or fork and just as their tops start to show new growth. If they are left in the ground too long in the spring and the tops start to grow out, they become woody.
Never had parsnips? Some mistakenly refer to them as white carrots, but while they may be related to carrots distantly, they are actually part of the parsley family. They are a cream-colored, gnarled, carrot-shaped root vegetable. They can be eaten raw but are best prepared by roasting, frying, grilling or steaming to bring out their distinct succulent flavor and nutty sweetness. They have a tan peel that is typically removed before use; peeling also removes their gnarly surface. The flesh is cream-white. They are a very versatile vegetable with recipes ranging from roasted side dishes, soups and stews, mashed, turned into fries, and even made into wine. They pair well with other root vegetables, too. Like potatoes or an apple, parsnips oxidize when exposed to air after their peelings are removed. If not prepared right away, cut parsnips should be placed in water to reduce the effect.
Being white in color, one would tend to believe that they offer little nutrition. Quite the opposite is true. According to the USDA [1], a half-cup serving of parsnips are high in heart-healthy fiber providing 3 grams of fiber and only 55 calories. They are a low-fat food yet a good source of numerous vitamins (especially C and K), minerals (especially folate and manganese), and antioxidants. (Note that the level of vitamin C is somewhat reduced with the cooking.)
Besides the home garden, parsnips are available at the supermarket and likely can also be found at the late fall and spring farmer’s markets. Spring is the best time to give them a try if you are new to parsnips. If you are lucky enough to find this once-a-year spring treasure, choose fleshy, fresh, firm, medium-sized and even surfaced roots. Avoid woody, over-matured, long, thin, and tail-like roots as they are off-flavored and have tough fiber. Also avoid soft, pitted, shriveled, knobby, or damaged roots.
Fresh parsnips should be stored in a plastic bag in the vegetable drawer of the refrigerator where they should last three to four weeks [2]. Use cooked, refrigerated parsnips within three days. Parsnips can also be frozen [3] for later use by cutting into 1/2-inch cubes, water blanching for 2 minutes, cooling promptly in cold water, draining, and packing and sealing into containers, leaving 1/2-inch headspace. Fully cooked parsnip puree may also be frozen for up to 10 months for best quality. Drying is another method for preserving parsnips as well.
For more information on parsnips, check out Growing Carrots and Parsnips in Home Gardens by the University of Minnesota Extension [4].

When you think of Iowa, maple syrup probably isn’t the first thing to come to mind. However, maple syrup is one of the state’s oldest agricultural crops dating back to pioneer times. Native Americans were the first to tap Iowa’s maple trees followed by early pioneers who also tapped maple trees for their annual supply of sweetener.
Today, Iowa has a small number of commercial producers mostly located in the northeastern part of the state and several small commercial or home-use only producers scattered across the state. According to the USDA 2017 Agricultural Census, Iowa reported 53 farms with 13,808 taps.[1] Producers use a variety of methods to collect and boil sap into syrup. However, the methods are much the same today as used by our ancestors. Small holes are drilled into the tree trunks (taps), sap drips into buckets or tubes below, and evaporators boil the clear sap into delicious maple syrup. The color of maple syrup varies depending upon when it was tapped. Late winter tapings yield a light brown syrup with color deepening as spring advances. Color is not an indicator of quality; maple syrup is graded by color with color affecting flavor. Grade A syrup is a light amber color, while Grade B is darker and thicker. Grade A is mild in flavor with Grade B syrups having a deeper, more robust maple flavor.
On the average, it takes 40 gallons of maple sap to make 1 gallon of pure maple syrup. A tree will produce 10-20 gallons of sap per tap on the average. A tree may have more than one tap depending upon its size/circumference.
While maple syrup is a sweetener, the nutritional benefits of maple syrup are numerous. One tablespoon of maple syrup contains 50 calories along with the following vitamins and minerals:
Maple syrup can be used as an alternative to sugar in cooking and baking in a 1:1 ratio. When used in baking, decrease the liquid by 3 to 4 tablespoons per 1 cup substitution. If no liquid is called for in the recipe, add about 1 tablespoon of additional flour for every ¼ cup of maple syrup. [3]
Iowa’s maple syrup season generally begins in late February or early March and runs 4 to 6 as six weeks. Warm daytime temperatures and cold nights are needed for the sap to flow; the season ends when the trees begin to bud. If you are looking for some early-spring family fun, a number of groups have planned events and demonstrations across the state to allow nature lovers of all ages to take part in this unique agricultural activity. Below is a listing of a few. Registration and fees may be required and pancakes and maple syrup might be included with some events.

The recently releasedFoods for Iowa 4-H Fairs – Quick Reference Guide (2023) lists “traditional vanilla buttercream made with butter, powdered sugar, extract, and milk” as an acceptable homemade frosting for baked goods exhibited or displayed at Iowa 4-H fairs. Identifying a safe “traditional buttercream frosting” recipe for exhibit has been a source of confusion for 4-H members and their families as well as County Extension Educators and fair judges. Store-bought, commercially prepared frostings that are shelf stable are acceptable for food product exhibits.
Food products exhibited at 4-H Fairs must be shelf stable or stable (non-perishable) at room temperature and not require refrigeration to be safe. Due to the various ingredients and quantities that may be incorporated into a homemade frosting, many frostings require refrigeration to be unquestionably safe. Three factors play a role in determining the safety of a frosting: acidity (pH), water activity (Aw), and percent of soluble solids (%Brix).
The acidity (pH) of a frosting is affected by the ingredients used. Traditional frostings made with dairy or eggs tend to increase pH making them more basic than acidic and susceptible to spoilage. Therefore, frosting made with cream cheese, whipped cream, or eggs requires refrigeration to inhibit spoilage and molding despite the fact that frostings are laden with sugar, known for its ability to inhibit microbial growth.
Water activity (Aw) is the measure of available water in a food product that can support microbial growth and affect the quality and safety of food. This differs from moisture content which refers to water bound to ingredients within the food. The FDA has established that a water activity (Aw) value greater than 0.85 on a scale of 0 (bone dry) – 1.0 (pure water) indicates a high-risk food product capable of facilitating the growth of microorganisms in the product. Sugar may lower the Aw while water or dairy can increase the Aw; fat has no effect on Aw.
Percent soluble solids (%Brix) in a frosting is determined by the amount of sugar available to bind up the available water to reduce bacterial growth. As %Brix increases, Aw decreases.
Due to these factors, frostings are considered TCS, foods that require either temperature or time control for food safety. TCS foods may allow pathogens to grow and possibly produce toxins when held at temperatures between 41-135 degrees F. (For additional information see: Food Safety of Frostings and Fillings by K-State Research and Extension.) To be considered a non-TCS food, the percent soluble solids (%Brix) must be above 65% and the Aw value less than 0.85.1
There are numerous recipes for buttercream frosting. It is not a given that all buttercream frostings meet the %Brix and Aw requirements to be a non-TCS food or safe without refrigeration. To determine the safety of a vanilla buttercream frosting for Iowa 4-H exhibits, three members of the AnswerLine team prepared an adapted version of the Simple Buttercream Frosting tested and considered stable at room temperature by K-State Research and Extension1. Milk (dairy) was substituted for heavy cream in the K-State recipe. The frostings were prepared at the individual homes of the team members using the same butter and powdered sugar; the percent of milk fat and vanilla extract were the two variables. The three samples were submitted to the Iowa State University Food Quality and Safety Laboratory for analysis of water activity and %Brix with results shown in the table below.
Table 1. Average water activity and % soluble solids of frostings tested.
Sample
Water Activity
% Soluble Solids
Sample 1 – Skim milk
0.788± 0.003
68.60 ± 0.30
Sample 2 – 2% Milk
0.812 ± 0.004
67.83 ± 0.23
Sample 3 – Whole Milk
0.808 ± 0.006
67.17 ± 0.35
All three samples met the requirements of a non-TCS food as recommended by K-State Research and Extension1 exhibiting an average Brix of 67.87% and an Aw value of 0.803.
Tested Vanilla Buttercream Recipe Required for use with Iowa 4-H Fair Food Product Exhibits. (All Iowa 4-Hers must reference and attach this blog to their write-up for full credit if a homemade frosting is used in the exhibit. Any change or addition of ingredients will be unacceptable and will result in disqualification.)
1 cup unsalted butter, slightly softened 4 cups powdered sugar ¼ teaspoon salt 1 teaspoon vanilla extract 2 Tablespoons dairy milk (skim, 2%, or whole)
Beat the butter, salt, and vanilla together until fully combined on medium speed. Reduce speed and add the powdered sugar and milk. Add the milk a teaspoon at a time to achieve the right consistency for the way you want to use the frosting. DO NOT use more than 2 tablespoons of milk. Slowly increase the speed of the mixer and beat until the frosting is light and fluffy.
What Does This Mean for Iowa 4-H Food Products?
It is highly suggested that exhibits be presented without frosting unless the frosting is part of the exhibit goal.
Example 1: My goal is to bake an angel food cake for exhibit at the fair. No frosting is needed for this exhibit. Cake recipe should be included with the exhibit.
Example 2*: My goal is to bake and frost a chocolate cake for my Dad’s birthday. I will also exhibit asimilar cake and frosting at the fair. Cake should be frosted with the tested vanilla buttercream frosting or with a commercially prepared frosting to assure that it is not a TCS food. No chocolate, cocoa, or other ingredient should be added to the tested recipe or commerical frosting. Recipe for cake and frosting (if homemade) should be included with the exhibit, along with this blog.
Example 3*: My goal is to learn to make a cake and a frosting for exhibit at the fair. Cake should be frosted with the tested vanilla buttercream frosting; no chocolate, cocoa, or other ingredient should be added to the tested recipe. Cake and frosting recipes, along with this blog, should be included with exhibit.
*For examples 2 and 3, another option is to prepare the product using any frosting desired; before serving, take pictures of the frosted product. Exhibit the product without frosting at the fair and note in the write up that the product is being exhibited without frosting due to food safety concerns. Add pictures of the frosted product to the write up and include the product recipe with the exhibit.
Homemade Cream Cheese, German Chocolate or Coconut-Pecan, Ganache, or 7-Minute frostings or fillings are not to be exhibited at the fair. They are potential TCS foods due to the range of water activity (Aw) in various recipes and should be stored in the refrigerator.
Decorator frostings of any type may be used when the goal is to decorate a cake. The cake may be food, cardboard, or Styrofoam and will be judged on design, neatness, originality, skill, and technique; the cake will not be tasted or judged on product characteristics.
Fresh or canned fruit, vegetable, or zest should not be used as decoration or garnish on a baked product or decorated cake.
When a glaze is desired, it should be made with powdered sugar and water only. No fruit juice or zest should be added.

Monk fruit sweetener is currently trending as a popular consumer choice as an alternative to sugar. Accordingly to market analysis by Data Bridge, the monk fruit sweetener market is expected to witness market growth at a rate of 5.40% in the forecast period of 2021 to 2028 and is expected to reach USD of 0.30 billion by 2028. The market is driven largely by health conscious consumers’ demand for a naturally derived sweetener, diabetic patients, and the awareness of negative health effects of sugar: obesity and diabetes. The added functional properties—anti-microbial, anti-inflammatory and anti-carcinogenic—are also driving the growing popularity of monk fruit sweeteners [1].

What is Monk Fruit Sweetener?
Monk fruit sweetener is derived from monk fruit, a small, green melon, actually a gourd, known as luo hang gu; it is native to southern China. Growing as a vine, monk fruit is an ancient fruit thought to have been cultivated by monks as early as the 13th century in the misty mountains of Guilin and used as a medicinal herb in traditional Chinese medicine. The fruit itself is unpleasant to eat. Instead, it is dried and used to make extract, granulated sweetener, powdered sweetener, and syrup [2]. Monk fruit is marketed under a variety of labels ranging from pure sweetener to added ingredients such as erythritol which may cause digestive issues for sensitive individuals.
The sweetness of monk fruit does not come from glucose or fructose; rather it is from mogrosides, an antioxidant extract of the fruit. Containing zero calories, zero carbs, and paleo-safe, monk fruit sweeteners are approximately 100-250 times sweeter than traditional table sugar. Monk fruit sweetener is less sweet than stevia which is approximately 300 times sweeter than table sugar [3]. When added to foods and beverages, a little goes a long ways.
Are Monk Fruit Sweeteners Safe?
Monk fruit was “generally recognized as safe” (GRAS) by the FDA in 2010 for use in food and beverages. While no human studies have been done, monk fruit is said to be safe for diabetics, children, and pregnant and breastfeeding women [4]. Monk fruit sweeteners have not been studied for weight-loss.
What are the Benefits or Drawbacks of Monk Fruit Sweetener?
In addition to the aforementioned benefits, monk fruit is said to be more palatable as it does not have the aftertaste that many users detect in other sweeteners. Further, it does not raise blood glucose levels or have side effects like gas or bloating that are often associated with some sweeteners.
Monk fruit sweetener is pricey due to the expense of processing and importing from China. The price, however, may be offset by the fact that only a small amount is used. For example, only a pinch of pure monk fruit sweetener may be needed for sweetening beverages and smoothies and if used for baking, 1-2 teaspoons may be equivalent to 1 cup of sugar. While it is not readily available at many supermarkets, it can be ordered from various websites. Some consumers have noted that it does not dissolve easily and they do detect a slight aftertaste. The sweetener tends to become sticky when exposed to air so storing in an airtight container avoids this problem.
How is Monk Fruit Sweetener Used in Cooking, Baking, and Preserving?
Monk fruit sweeteners should not be substituted 1:1 for sugar unless the manufacturer indicates so. Some monk fruit sweeteners are made with a mix of sugar alternatives and/or fillers, so be sure to read the label. Recipes and tips for cooking and baking can be found on the website of some of the monk fruit sweetener labels. Available as a granular, powder, and syrup, each type works best in different applications. Stable at high temperatures, the sweetener does not burn or give a sour taste when used for baking and cooking.
Baked products made with a sugar substitute may have different characteristics than those made with sugar. Using a sugar substitute may affect the texture, color, volume, structure, flavor, and keeping qualities. Sugar, like every ingredient, serves a purpose in baked goods beyond adding sweetness and flavor. Sugar contributes to moistness by binding water, provides structure and leavening, aids in browning and crispness via the maillard reaction, and acts as a preservative by slowing bacterial growth. While some functions and characteristics can be replaced by sugar substitutes, others are unique to sugar.
When used for baking, pure monk fruit sweetener may be less desirable as it does not have the bulk that sugar provides to a recipe. When mixed with erythritol, baking is more successful as erythritol adds bulk to the recipe resulting in a product that looks and tastes more like a product made with sugar.
Monk fruit sweetener should not be used for canning. To date, there has been no testing with monk fruit sweeteners to determine their effects on pH in home canned foods [5]. Utah State Extension [6] offers this explanation: “The sweetness of monk fruit does not come from the traditional fructose sugar molecule in the fruit. The monk fruit sweetener chemicals are extracted from the monk fruit and then blended with something to bulk it up. Each product might be different regarding pH and what is called the pH buffering capacity.” For this reason, canning with monk fruit sweeteners is currently not recommended.
Freezer jams and jellies can be successfully made with monk fruit sweeteners along with a freezer pectin. Monk fruit can also be added to fruits prior to freezing.
Monk fruit sweetener is a safe alternative to sugar and one way to reduce consumption of added sugars and/or manage caloric intake. It is important to do your research and know what you are buying for your intended use. Be sure to read the label and use the product correctly.

Eggnog and holidays seem to go hand in hand. While prepared eggnog is readily available at the supermarket, there is nothing like homemade eggnog. Since eggs are a main ingredient of homemade eggnog, homemade eggnog has the potential to spoil holiday fun and cause Salmonella poisoning from the use of raw or undercooked eggs. Salmonella bacteria is a potential risk even when refrigerated eggs with clean, uncracked shells are used.
How to convert a special family eggnog recipe into a safe recipe
Use a cooked egg base. FoodSafety.gov recommends a cooked egg base for eggnog. This is especially important if you are serving people at high risk for foodborne infections: young children and pregnant women (non-alcoholic eggnog), older adults, and those with weakened immune systems. Eggs must be cooked to 160 °F to kill bacteria that may be present such as Salmonella. A cooked egg base or custard is made by heating half of the the milk and/or cream to almost boiling and ever so slowly adding the beaten egg yolks (or sometimes the whole egg) and sugar (or any sugar substitute). Continue to cook and stir the mixture gently until an internal temperature of 160 °F is reached. At this temperature, the mixture will firmly coat a metal spoon and remain separated when a finger is drawn through it. Do not let the mixture go beyond 160 °F as above that temperature, the eggs are likely to curdle. (If curdling occurs, put the mixture in a blend and blend until smooth.) Place the mixture in a bowl of ice water to stop the cooking action and prevent curdling or further curdling and then refrigerate.
Use pasteurized eggs yolks.Eggnog may be safely by using whole, liquid or pasteurized eggs or egg substitutes in place of raw eggs. Pasteurized eggs are found next to regular eggs at the store. Commercial pasteurization of eggs is a heat process at low temperatures that destroys any Salmonella that might be present without having a noticeable effect on flavor or nutritional content. Even if you are using pasteurized eggs for your eggnog, both the FDA and the USDA recommend starting with a cooked egg base for optimal safety. When egg substitute products are used, some experimentation might be needed to figure out the right amount to add for the best flavor.
Use alcohol to inhibit bacterial growth.While alcohol will inhibit bacterial growth, adding alcohol (in amounts recommended by most recipes) will not be sufficient to kill bacteria. However, if one wants to use alcohol, Cooks Illustrated suggests that 1 1/2 ounces of 80 proof liquor per egg and three weeks of aging in the refrigerator is sufficient to kill bacteria when dairy is omitted until ready to serve. Such was conclusively proven by microbiologists at Rockefeller University where salmonella bacteria was purposely added to eggnog and analyzed over a three-week period. By the three-week mark, the alcohol had rendered the eggnog completely sterile.
Substitute egg whites. If a recipe calls for adding beaten egg whites to the hot egg/milk custard, use pasteurized egg whites. While pasteurized egg whites do not whip to the same volume as raw egg, they are safe. It has not been proven that raw egg whites are free of Salmonella bacteria; NOR has it been shown that when adding them to the hot milk/egg custard, the custard remains hot enough to kill any bacteria. Another good substitute is whipping cream whipped to soft peaks added at the time of serving.
Here’s to a safe and worry-free holiday! Follow these suggestions for your favorite eggnog recipe to ensure everyone can enjoy delicious, creamy homemade eggnog without worry of a foodborne illness.
