Start by peeling an apple and slicing it very thinly on a mandoline.
Meanwhile, bring a shallow pan of slightly diluted simple syrup (I used 2 cups water and 3/4 cup white sugar) to a light boil on the stove.
Slide the slices one-by-one into the lightly boiling syrup.
*Cook's note: Feel free to use a flavored or infused simple syrup (a one-to-one water to sugar heated until dissolved) such as ginger, lemon or orange.
Sprinkle with any seasonings you like,
Bake at 220°F for 45 minutes or until desired doneness, rotating the baking sheet halfway through. Since the apple chips won't fully crispy until they've cooled, remove one from the oven to test for crunch.
