This was recommended to us by a caterer. It is an inexpensive way to buy parchment paper once. It is an incredible, never stick, baking liner that can be cut to fit any pan and reusable for hundreds of times. Great for cakes, cookies, brownies, to catch drips from fruit pies and even on pancake griddles! Safe up to 550 degrees. Sponge clean. Do not expose to open flame.
