Funny you should ask this. I saved the Walmart free Live Better magazine from Sept. 2014 here in Canada. It was titled Reinventing Turkey for our Canadian Thanksgiving. It had a section on apple recipes. I will try to type out their recipe for
Homemade Apple Chips. 225F-2hours
1 and 1/2 tsp. granulated sugar
1/8 tsp nutmeg
2 gala apples, unpeeled, cored and sliced thin on a mandolin
Position oven racks in top and bottom thirds of oven. Preheat to 225F. Line 2 large baking sheets with parchment paper.
Stir sugar and nutmeg in a small bowl.
Prepare apple slices and arrange slices in a single layer on prepared sheets. Sprinkle with nutmeg/sugar mixture.
Bake in top and bottom thirds of oven until edges are ruffled.(1hour) Flip apple slices, switch sheet positions on oven racks and continue baking until apple slices are golden (1 more hour) Slices will crisp up as they cool.
I have not tried this recipe but I saved the magazines as it had several I want to do.
