Cast-iron cookware. Cast iron's ability to withstand and maintain very high cooking temperatures makes it a common choice for searing or frying, and its excellent heat retention makes it a good option for long-cooking stews or braised dishes. Because cast-iron skillets can develop a non-stick surface, they are also a good choice for egg dishes. Other uses of cast-iron pans include baking, for instance for making cornbread, cobblers and cakes. Most bare cast-iron pots and pans are cast as a single piece of metal, including the handle.
