Cheez Whiz is a processed cheese sauce or spread sold by Kraft Foods. It was developed by a team led by food scientist Edwin Traisman (1915–2007). While many sources give its national debut as 1953, it was advertised by Kraft and retailers in several states in late 1952. Orangish-yellow in color, it usually comes in a glass jar and is used as a topping for various foods, including corn chips and hot dogs. It is also frequently used as the cheese in a Philadelphia-style cheesesteak. It is marketed in Canada, Mexico, the Philippines, the United States, and Venezuela.
