Which of the following is an example of a non-stick cooking surface?

A non-stick cooking surface is designed to prevent food from adhering to it, making it easier to cook and clean. Teflon, which is a brand name for polytetrafluoroethylene (PTFE), is a common non-stick coating applied to cookware. When pots and pans are coated with Teflon, they have a smooth surface that reduces friction, allowing food to slide off easily and preventing it from sticking during cooking. This quality makes Teflon-coated cookware particularly popular for tasks such as frying eggs or pancakes.

In contrast, cast iron and stainless steel surfaces do not possess the same non-stick properties. Cast iron can be seasoned to create a certain level of non-stick capability, but it requires maintenance and may not be classified as truly non-stick in comparison to Teflon. Stainless steel is durable and versatile but is prone to sticking if not properly preheated or oiled. A baking stone, while excellent for creating a crisp crust for baked goods, does not provide a non-stick surface and typically requires parchment paper or other non-stick sprays to prevent sticking.
