Forget store bought snacks and make your own afternoon treat of sweet and spicy baked apple crisps. Store in an airtight container for up to a week.
Preheat oven to 200°F. Line two or three baking sheets with parchment paper; set aside.
Using a mandoline or a serrated knife, cut apples crosswise into 1/8-inch-thick slices. Arrange slices in a single layer on baking sheets. In a small bowl combine sugar and chipotle pepper. Sprinkle apple slices with half of the sugar mixture. Use a pastry brush to brush mixture over apple slices to cover evenly. (Or, place the sugar mixture in a small sieve. Hold the sieve over the apple slices and stir the mixture with a spoon to evenly disperse the sugar mixture over the apples.) Turn apple slices and repeat with remaining sugar mixture.
Bake for 2 to 2 1/2 hours or until crisp, turning apple slices and rotating pans every 30 minutes. Cool completely on wire racks.
Place cooled apple crisps in an airtight container; cover. Store at room temperature for up to 1 week.
