To dry apples, first peel them and cut them into thin slices. Then, dip the slices in lemon or pineapple juice, which will prevent them from turning brown during the drying process. Next, spread the slices on a baking sheet and put them in the oven. Turn on the oven to the lowest temperature setting and dry the slices for 1 hour on each side. Once both sides are dry, turn off the oven and let the apples dry for another 3 hours before serving or storing them for later.
