One of the standout features of cast iron flat grill pans is their ability to retain heat. Unlike other materials, cast iron's density allows it to maintain high temperatures for extended periods, which is ideal for searing meats and achieving that perfect grill mark. This characteristic not only enhances the flavor of foods but also ensures even cooking. Whether you're grilling vegetables, burgers, or pancakes, the uniform heat distribution of a cast iron flat grill pan guarantees consistent results every time.
