You may be afraid of canning foods at home because it seems dangerous. If you follow step-by-step instructions for canning fruits and vegetables, your sauces, jams, pickles and tomatoes will be just fine. You can always tell if a jar was properly sterilized by looking at the color of the canned food or the lid of the jar. A bowed or rounded on top jar points to botulism. A lid that doesn’t pop when you open a jar indicates that the jar was not sealed properly. If the liquid has a strange color that looks brown or black, it means that something went wrong. If the food looks slimy or moldy, you should throw it in the garbage.
Canning offers a number of benefits compared to freezing. First, you do not need a freezer for food when it’s canned. Second, some foods, such as pickles and peaches, taste better when canned.
Canning is more complicated compared to freezing and drying. It also preserves the least amount of nutrients in food. In contrast, dried foods are great sources of nutrients and energy. You do dry your foods the old-fashioned way: by hanging them in a dry place and letting them dry or by using a dehydrator or an oven. Just like with freezing, blanching vegetables before you start the preservation process helps them keep their nutritional value. Slicing or dicing produce into pieces helps it dry faster and makes the process easier.
Agriculture experts like Jeff Hill know about the importance of strictly following the rules. Use a screen when drying food outdoors. Cover the produce with a cloth to safeguard it from insects. Once the food dries, keep it in the refrigerator or in a dark cold place.
