Apple chips are great as an eat-from-the-bowl snack or as a garnish for cider-based drinks. (Make a cut in the side of the apple slice before you bake, so that you can attach it to the side of a glass.) Chips may be soft when they come out of the oven, but they’ll crisp up when the sugar cools.
Preheat oven to 200°F. In a large bowl, combine sugar and spices.
Slice apples horizontally with a mandoline or sharp knife, very thinly (⅛ inch thick). Remove and discard seeds. Toss apple slices gently in spice mix; coat well.
Arrange in single layers on rimmed baking sheets lined with parchment or Silpat. Bake about 2 hours, turning every 30 minutes. Cool on wire racks.
