A pot has tall sides and two loop handles while a pan has one long handle and is shallow. Pots are used to simmer or boil liquids that completely cover the food in order to cook it from all sides. Pans are used for cooking methods including reducing, sauteing, searing, or frying that use high heat to obtain browning. Cast iron is the best type of cookware material for heat retention. These incredibly durable pans maintain heat very effectively for deep-frying and searing steaks. Cast iron may last for many generations if cleaned and kept properly. Because they are designed for high-performance cooking and are very effective and long-lasting, these pans are appreciated in commercial kitchens.
