Resources for Teaching Children the Science of Food Preservation

Summertime is often a good time to introduce children to hands-on experiences that use skills learned in school. However, new skills can be learned anytime and food preservation is one such activity that uses reading, math, and science principles. It is also a great way to teach new or life skills, pass on family activities/heritage, and enjoy produce all year long. If it is to be a summertime activity, now is a good time to prepare for the adventure.

Children learning preservation skills from grandmother and grandfather

Activities should be geared to the child’s age and/or ability. Young children may enjoy slicing bananas and dehydrating them. Older children may enjoy making strawberry jam for the freezer or canning for shelf storage. Every food preservation adventure should begin with clean hands, equipment, workspace, and fresh, quality fruits or vegetables. If the project includes canning, a tested recipe from a reliable source should be chosen. Easy, tested recipes can be found with the National Center for Home Food Preservation, USDA Complete Guide to Home Canning, Mrs. Wages mixes, or Sure-Jell/Ball® pectin.

The National Center for Home Food Preservation at the University of Georgia has updated their curriculum Put it Up! Food Preservation for Youth. These educational lessons are written for youth, from 4th to 12th grade, but could be used for anyone to understand the science of safe food preservation.

This curriculum can be used for schools, summer camp instructors, parents, 4-H agents, other Extension educators, farm to school programmers, and classroom teachers…anyone who is comfortable with food preparation and food preservation, or is willing to learn! A request for access is needed to obtain the curriculum.

The series is composed of six different food preservation methods: boiling water canning, making jam, pickling, freezing, drying, and pressure canning. Each method is divided into a beginning hands-on activity and an advanced hands-on activity. Activities may stand alone or be sequenced for cumulative learning. In addition to step-by-step procedures, reflection questions, and ideas for experimentation, each method also includes additional activities: a science-based fill-in-the blank challenge, a history-based word search, a glossary, a resource list, a knowledge test, and more. Each preservation activity is also accompanied by a legal-sized “poster” with simplified step-by-step instructions to be printed and posted as a checklist to help keep everyone on track and working together.

Other resources to use with children learning food preservation include:

If you love home food preservation, share your enthusiasm with a child. It is a lifelong skill and a great bonding experience!

DIY Corned Beef

Corned beef and cabbage traditionally comprise a St. Patrick’s Day meal.  While St Patrick’s Day is celebrated around the world, corned beef is strictly an Irish-American tradition.  It isn’t the national dish of Ireland nor the food you would eat on St. Patrick’s Day in Dublin.

The early Irish immigrants are credited for giving us corned beef, however.  In their homeland, St. Paddy’s Day was celebrated with boiled bacon.  Being too poor to afford the high price of pork and bacon products, they turned to a cheap cut of beef (brisket) and adapted Eastern European and Jewish brining methods to prepare the meat.  “Corned” has nothing to do with corn; instead it refers to the corn-sized salt crystals (saltpeter) used during the brining process to cure or pickle the meat.  Their new celebration dish was paired with cabbage as it was one of the cheapest vegetables available to them.

Corned beef is essentially beef cured in a salt brine with pickling spices for added flavor. It is readily available around St Patrick’s Day in ready-to-cook form and available at most delis year round. It can also be made at home using fresh brisket or any other cut of beef desired.

DIY CORNED BEEF

Regardless of recipe, making corned beef is a three-step process and is easily done. It does require curing time so factor that into the preparation time. The biggest difference in recipes is the pickling spice mix.

Step 1.  Make a salty curing brine of water, kosher salt, and pickling spices with any combination that appeals in flavor. Pickling spice, mustard seed, allspice berries coriander seeds, peppercorns, juniper berries, bay leaves, cinnamon stick, cloves, and ground ginger are just some of the pickling spice suggested.   The brine for corned beef usually contains a small amount of sugar (white or brown) and pink curing salt. Sugar helps to cut some of the harsher effects of salt and enhances flavor.  The brine is boiled and chilled.  Boiling activates the pickling spices to flavor the brine and insures that the sugar and salt are fully dissolved.

Step 2. Add meat to the chilled brine and marinate in the refrigerator. This is perhaps the most difficult as it involves finding a sealable, non-reactive container big enough for brisket and brine to marinate for 5-10 days and a space large enough in the refrigerator. The container should be plastic, glass, or stainless steel. Other metal containers will react with the brine solution and give the meat a metallic flavor.  A large zip bag on a tray is a good option if the brisket is not too big and both will fit in the refrigerator. The brisket should be turned daily during this time to insure that it is cured evenly and thoroughly.

Step 3.  Rinse and simmer in the same way as a prepared corned beef brisket from the supermarket.  The brisket is rinsed to remove the brine and simmered in water covering the meat with more pickling spices for at least three hours or until tender.  Once the meat is tender, it should be sliced against the grain for serving. Cutting through the muscle fibers shortens them and makes each piece easier to chew. 

INGREDIENT FUNCTIONS

Salt (sodium chloride), in general, acts as a preservative and by osmosis action pulls water out of the meat cells as well as any bacteria, killing or preventing it from multiplying by dehydration.  Even though salt is a dehydrator, it also produces a contradictory reaction making brined meat moister and juicier by changing the shape of the cell protein to hold more juice.  Care should be taken in the amount of salt used in the brine.  1Ruhlman and Polcyn recommend a 5-percent brine, 5 ounces of salt per 100 ounces of water. Kosher salt is preferred but it is not absolutely necessary; table or pickling salt can be used.  Since kosher salt has larger crystals, a lesser amount of finer grained salts should be used.  (See this Morton Salt conversion table.)

Pink curing salts are a mixture of sodium chloride (93.75%) and sodium nitrite (6.25%) and serve as a preservative by inhibiting bacterial growth as well as giving cured meats their characteristic reddish color and savory, sharp flavor. Pink curing salt used for brining have such names as InstaCure #1, Prague Powder #1, DQ Cure #1 and Modern Cure #1.  It may be necessary to order curing salt as it may not be readily available in local supermarkets.

Pink curing salt should not be confused with Himalayan salt which is also pink; the two salts are only similar in color and sodium chloride content. Curing salts are colored pink so that they are not confused with table or pickling salt as, if used in quantity, they are toxic. The National Center for Home Food Preservation recommends that consumers use 1 ounce of curing salt for every 25 pounds of meat or one level teaspoon of cure for 5 pounds of meat.

There is some controversy over the use of sodium nitrite in curing meats as with frequent consumption of cured meat, some studies have shown a risk of certain types of cancer. (Per University of Minnesota scientists, “based on available evidence to date, nitrite as used in meat and meat products is considered safe because known benefits outweigh potential risks.”2) Because nitrites are also found in vegetables, it is estimated that around 90 percent of the nitrite in our bodies comes from vegetables, while just 10 percent comes from processed meats.2   If curing salt is not used, the brined meat must be cooked immediately after curing and one should expect grey meat; salt used in the brine turns the meat grey.

DIY Corned Beef can be a rewarding experience and a “TaDa!” moment! There is great joy in doing something ourselves and having control of the ingredients we use.
