Soft serve

Soft serve is a type of ice cream that is softer than regular ice creams as a result of air being introduced during freezing. Soft serve ice cream has been sold commercially since the late 1930s.

History

Over Memorial Day weekend of 1934, Tom Carvel, the founder of the Carvel brand and franchise, suffered a flat tire in his ice cream truck in Hartsdale, New York. He pulled into a parking lot and began selling his melting ice cream to vacationers driving by. Within two days he had sold his entire supply of ice cream and concluded that both a fixed location and soft (as opposed to hard) frozen desserts were potentially good business ideas. In 1936, Carvel opened his first store on the original broken down truck site and developed a secret soft serve ice cream formula as well as patented super low temperature ice cream machines.

Dairy Queen also claims to have invented soft serve. In 1938, near Moline, Illinois, J. F. McCullough and his son, Alex, developed their soft serve formula. Their first sales experiment was August 4, 1938, in Kankakee, Illinois at the store of their friend, Sherb Noble. Within two hours of the "all you can eat" trial sale, they had dished out more than 1,600 servings — more than one every 4.5 seconds.
