Chef's Planet Universal Non Stick 40 Inch by 12 Inch Bake Liner
This product is designed to make cooking easier and enjoyable.  Scrubbing baken-on food from your pans isn't.  So don't.  Use the Universal Nonstick Bakeliner and be a baking genius.  It puts a nonstick layer between your goodies and your pans.  Foods cook more evenly and your baked food will slide right off.  Spend more time doing what you love and less time doing what you don't.
