I was thinking more in terms of dried staples. Field corn to grind into meal, and pintos or the like. (I guess leatherbritches would serve, also, though I don't know if there are enough seeds in most modern varieties of greenbeans to balance out the protein with cornmeal.)

I'm thinking mainly of food combinations for protein that don't require special equipment. I work with mostly indigent folks who don't have the price of the canning jars and lids, but who could dry corn and beans (and tomatoes!) to get them through the winter. Because I live in a rural area, most of these folks do grow substantial gardens that keep the carbs and fresh veggies coming in season. But they don't have, and can not afford canning supplies, and most do not preserve much from their gardens to get them through winter. They buy staples like dried beans, flour and cornmeal, which until recently have been cheap, and could be bought for less than what it cost to raise them.   They may try to stock a freezer, but it is not unusual for their electricity to be disconnected once or twice a year for non-payment, and so they are likely to lose anything they have frozen. Drying food is the most economical and sure method for them.

Who knows? Maybe the time is coming when that will be true for many of us with currently moderate incomes. These heavy rains and floods, aside from the immediate toll on the lives of those in the midst of the waters, are going to have a big impact on already rising prices of basic foods.
