Add lemon juice to apples and mix, then sprinkle pumpkin pie spice slowly over the apples while continuing to mix so spice is evenly distributed.

In dehydrator, line apples on racks and dry over night (8-10 hours) at 135°. When they first come out, they wont be super crispy, but they will in time, at least an hour. Place crisps in ziplock or tupperware to store.

Apples can also be baked on baking sheets. Pre-heat oven to 225° and bake for 45 min to an hour.
