Skillets are a type of cookware that is used for frying, sauteing, and other cooking techniques. Frypans and PANS are two types of skillets, with frypans being larger and having deeper sides than PANS. Frypans are typically used for larger items such as steaks, while PANS are better suited for smaller items such as eggs or pancakes. Skillets are made from a variety of materials, including cast iron, stainless steel, aluminum, and copper.
