I love Apples, but sometimes you end up with some that are a bit bruised, although that can be trimmed off the apple, I prefer to take these and make apple chips. In the directions it says to use parchment paper but I tried that once and the apples stuck so bad I could not get them off. I have been lining the racks with foil and spraying them with a bit of oil. Works great and they are easy to remove. I have been sprinkling mine with cinnamon sugar..really really tasty!
