Don't throw away the scraps of dough!  When you're trimming your crusts, there's bound to be some scraps.  There are a lot of things you could do with those scraps, but my favorite is to put them on a baking sheet and sprinkle cinnamon sugar all over them.  Place them in the oven with the pie and bake for a few minutes, just until puffed and golden.  Soooo good, a little sweet flaky treat!!
