Preheat oven to 225 and line a baking pan with parchment paper or aluminum foil.  Place the sliced apples on the pan and sprinkle with the lemon juice.

Mix the spices together and sprinkle half on one side of the apples.  Turn the apples over and sprinkle with the remaining spices on the other side.

Bake for 60 minutes.  Flip the apple slices over and bake for an additional 60 minutes.  Turn off oven, but do not remove the apples.  Allow them to cool as the oven cools.
