We used to pick fruit that was close to being ripe, slice pears or apples really thin, put the slices on a towel and and let dry on the screened in porch.
Peaches were cut into halves and seeds removed. We also put them on towels, cut side up and let them dry on the screened in porch. After a few days, just turn them over. It takes about two or three times on each side to make dried fruit to eat in the winter.
I’d love to dehydrate things naturally, but TN is *wet*!
