The wings will be their crispiest if they don’t pool in their own oil. If you have a wire rack that fits in your baking sheet – use it! Otherwise, when you remove the pan from the oven, carefully tilt it into the sink. A turkey baster works well for this. And you can always remove the wings to a bowl while you do this step to make it easier. If the wings haven’t rendered too much oil though, don’t worry about it.
