We eat dehydrated foods every day. Everything from macaroni and cheese to instant cake mixes and soup mixes are dehydrated. Since your family is already accustomed to the convenience of these foods, you'll love adding these #10 cans into your food storage program. These foods offer a great way to provide meals in an emergency and they're generally inexpensive. Most rehydrated fruits, vegetables, and textured vegetables proteins will rehydrate in about 20 minutes in warm or hot water. For this reason, we recommend you maintain adequate water storage with your food storage program.
