A cast iron skillet is a heavy cooking pan made from molten iron that is poured into a mold. Known for its excellent heat retention and even cooking, it is ideal for frying, baking, and sautéing. These skillets can be used on the stovetop or in the oven, making them versatile kitchen tools. One of the key benefits of a cast iron skillet is its natural non-stick surface, which improves with seasoning over time. Proper care, including regular seasoning and avoiding soap, can help maintain its durability and performance for generations, making it a favorite among both home cooks and professional chefs.
