With a pan without a non-stick coating, you can fry at a high temperature and sear your food quickly. This gives you a crispy layer and no juices are lost. You have to grease the pan well to prevent food from sticking. Pans without a non-stick coating are available in different versions. For example, they're usually made of stainless steel or cast iron. It differs per pan whether you clean it in the dishwasher or have to wash it by hand.
