Non-stick coatings are special layers applied to cookware, such as frying pans and baking sheets, to prevent food from sticking during cooking. These coatings are often made from materials like polytetrafluoroethylene (PTFE), commonly known as Teflon, or ceramic compounds. They make cooking and cleaning easier, allowing food to slide off surfaces without much effort. The effectiveness of non-stick coatings can vary based on their quality and how they are used. To maintain their performance, it is important to use utensils that won't scratch the surface, such as silicone or wooden tools. Additionally, proper care, like avoiding high heat, can prolong the life of these coatings.
