You can also dry a lot of the fruits and veggies. One of my best memories is going up into the attic and getting a paper bag of dried green beans. Seems that when Grandma hung them up on strings she'd sewed through them, she called them leather britches. They got hung out of the weather on the porch, and since most porches then were in the front, you could always tell if a housewife was thrifty and hard working by the curtain of drying beans.
