nonstick

Nonstick refers to a surface treatment or coating applied to cookware and baking equipment designed to prevent food from adhering during cooking and baking. The most common nonstick coating is polytetrafluoroethylene (PTFE), commonly branded as Teflon, which consists of a fluoropolymer resin created through the polymerization of tetrafluoroethylene. This synthetic coating creates an extremely smooth, low-friction surface that reduces the need for added fats and oils during cooking. Alternative nonstick coatings include ceramic-based compounds, silicone, and other fluoropolymers. The effectiveness of nonstick surfaces diminishes with use, scratching, and exposure to high heat, affecting the coating's longevity and performance over time.

Nonstick coatings are employed in a wide range of cookware including frying pans, saucepans, griddles, and baking sheets. They are particularly valued for cooking delicate foods such as eggs, fish, and pancakes that are prone to sticking to uncoated surfaces. Nonstick surfaces reduce the requirement for cooking fats, enabling healthier preparation methods and facilitating easier food release and cleanup. They are standard in commercial kitchens and home cooking for applications requiring minimal oil or butter, such as crepe preparation, egg cookery, and low-fat sautéing. However, nonstick cookware performs poorly at very high temperatures and may not develop the browning or crust desirable in techniques such as searing or pan-frying.
