A medium depth pan that generally has flared or rounded sides but is sometimes found with straight sides. It has a flat bottom and wide mouth, which accelerates the evaporation of liquids. A chef's pan most often will have a long handle and a tight fitting cover. It is made of a metal with a thick ground base that allows temperature changes to occur rapidly as the level of the heat applied to it changes, either increasing or decreasing for the best heat conduction. Chef's pans are available in a variety of sizes such as 2, 3, 4, 5, or 6 quart. The height of the sides make it easier for sautéing, frying or steaming greater amounts of foods, allowing sufficient space for turning and stirring of the contents. Chef's pans are very similar to saucier pans and either pan can be used interchangeably.
