2 apples, thinly sliced
2 tsp. granulated sugar
1/2 tsp. cinnamon
Preheat your oven to 200 degrees. In a large bowl, toss apples with sugar and cinnamon.
Place a metal rack inside a rimmed baking sheet. Lay apple slices on top of the chosen rack, spacing them so that no apples overlap.
Bake for 2 to 3 hours, flipping apples halfway through, until apples dried out but still pliable. (Apples will continue to crisp while cooling off.)
