2-4 fresh apples
Preheat oven to 200 degrees.
Slice apples as thin as possible - using a sharp knife or a mandolin for 1/8” slices.
Put slices in a bowl, toss with 1 tsp. of cinnamon, then spread out on a parchment paper covered baking sheet.
Bake in oven until crisp, approximately 2 hours. Once crisp, remove from oven and let cool for an hour. Store in an airtight container for a few weeks.
