For years professional have baked their goods on inert silicone-impregnated mats. These simple, inexpensive, oven-proof, non-stick sheets slide into baking trays and are now quite common in households like ours. Instead of consuming rolls of aluminum foil or parchment paper, you just lay everything out on these reusable durable mats, and bake. The nicely-browned goods slide off with no effort and no added grease. There's less burn on the bottom, too. Multiple mats can feed one expensive baking tray for serious cookie production. Clean-up is a simple rinse. As an added bonus, they make great kneading boards. The mats also roll up for easy storage. We've used several of the five brands available. So far, they all seem similar. Silpat was the original, but SiliconeZone is the least expensive I've seen.
