Fry sauce is Utah's defining condiment: roughly equal parts mayonnaise and ketchup, sometimes with sweet pickle relish, served with every order of French fries from Crown Burgers to Apollo to fast-food drive-throughs.

Don Carlos Edwards, founder of the Arctic Circle burger chain, invented fry sauce in 1948 at his Salt Lake counter when a customer asked for mayonnaise mixed into the ketchup. Within a decade the condiment spread across Utah; by the 1980s every Wasatch-front burger counter, drive-through and even McDonald's franchises in Utah served it. The 50/50 mayo-and-ketchup ratio is the canonical form, though commercial brands add pickle relish, paprika or buttermilk.
