A cast iron pan is a type of cookware made from molten iron that is poured into molds. Known for its excellent heat retention and even cooking, it is often used for frying, baking, and sautéing. Cast iron pans can be used on the stovetop or in the oven, making them versatile kitchen tools. These pans require special care to maintain their non-stick surface and prevent rust. Regular seasoning with oil helps create a protective layer. With proper maintenance, a cast iron pan can last for generations, becoming a cherished item in many kitchens.
