Read more Read more How to Cook with Nonstick: Never use cooking spray. Aerosol cooking spray leaves a gummy residue that is difficult to remove, and that residue will cause food to stick. Instead, use an oil mister filled with olive or vegetable oil, or dab a bit of oil on a paper towel and carefully wipe the interior of the pan. Use the correct heat setting. Use low heat for warming, simmering and preparing sauces; use medium heat for frying, grilling, sautéing, searing or stir-frying; use high heat for boiling or reducing liquids. Preheat the pan. Nonstick cookware can take a minute or two longer to preheat compared to aluminum or stainless steel cookware. For best results, make sure your nonstick pan is heated to the proper temperature before adding food.
