Choose ripe, fresh fruits to dry. Pick over damaged or soft fruits for composting. Wash and dry the fruit.
Mix 2 cups of lemon juice with 2 cups of cold water in a deep bowl. Slice the fruit in same-size pieces into the mixture. Soak the fruit slices for at least 10 minutes.
Remove the fruit slices from the mixture with a slotted spoon. Place them in a single layer on a paper towel to wick off excess moisture.
Spread out the fruit slices evenly in a single layer on a dehydrator screen. Set the fruit dehydrator to 140 degrees, and activate it.
Remove the dehydrator cover every four to six hours to turn the slices with a pair of tongs. Resume drying until fruit is leathery, and there is no sign of moisture. Drying times vary by moisture content and slice sizes.
Turn off the dehydrator heat when fruit appears brown and dry. Leave the fruit in the warm dryer for 30 minutes to finish drying without getting scorched.
Store dried fruits in an airtight container in a dry place. Label, and consume within one year.
