Also called a skillet, this long-handled, usually round pan has low, gently sloping sides so steam doesn't collect within the pan. It's used for frying foods over high heat, so it should be thick enough not to warp and should be able to conduct heat evenly. Frying pans come in various sizes, usually 8, 10 and 12 inches in diameter. Electric frying pans or skillets are often square or oblong in shape. Their heat is controlled by an adjustable thermostat unit that can be detached when the skillet is washed.
