Though I never peel apples before eating them out of hand, I sometimes find myself with a pile of peels after making a pie or tart. They could be composted, but I think I'd rather roast them to make delicious cinnamon-apple chips. (Or flavour some bourbon.) Photo by Jason Popesku.
Click the link below for exact measurements and ratios, but all you really need to do is toss the peels with a bit of butter to coat and then sprinkle on some cinnamon sugar, stirring to coat. Pop them in oven at 200C until they brown on the edges. Let cool, then toss with more cinnamon sugar. Put them in your mouth and chew.
