Corn, beans, okra, meats, fish, poultry, soups, broths, and other low acid foods must be pressure canned. Sadly, pressure canning has a bad rap and many folks shy away from it.
Canned foods don't require refrigeration so you don't have to worry about a power outage. Canned foods like beans (black beans, kidney beans, and so forth) are cooked and ready to add to your favorite recipes--saving time, money, and energy.
