Made by a French baker in 1965, Silpat non-stick oven mats free your baking from parchment sheets and greasy coatings. Made with food-grade silicone and reinforced fiberglass mesh, the two half-sheet mats cook evenly, release easily and eliminate the need to grease cookware with butter or oil. To use, line a baking pan or cookie sheet with the mat, top with cookie dough, frozen appetizers or other sweet and savory treats, and bake.
