So here's my tip: cut a foil star! I have done this several times now and it has worked every time!!! I am so excited about it. Maybe you already thought of this and if so, good for you!!!
For everyone else, seriously you have to do this. Don't ever cut those silly little strips of foil again.
Take a piece of used foil [see, I'm
Then unfold the piece of foil and bend down the corners so that it's got four little "legs." Bend up the star points that you created with your cuts and there you go! Stick that on top of your pie (or in the case of this photo example: a quiche) and bake away!
