Origin and story

The origins of soft serve are widely attributed to several figures, including Tom Carvel (whose ice cream truck broke down in 1934) and Dairy Queen (which began serving soft serve in 1938).

Soft serve is typically served at a higher temperature (around 25°F or -4°C) than traditional hard-scooped ice cream, contributing to its smoother, less icy texture.

Ways to celebrate

Soft serve exists because of a flat tire — an inconvenience that turned into a permanent business idea over a single holiday weekend.

Meet the man with the broken-down truck

Over Memorial Day weekend in 1934, Tom Carvel got a flat tire on his ice cream truck in Hartsdale, New York, pulled into a parking lot, and started selling his already-melting ice cream to passing vacationers — within two days he'd sold his entire supply and realized both soft ice cream and a fixed location could work as a business.

Know the rival claim

Four years later, in 1938, J.F. McCullough and his son Alex developed their own soft-serve formula near Moline, Illinois, running their first sales test on August 4, 1938 at a friend's store in Kankakee — a company that would go on to become Dairy Queen.
