Is there anything more tantamount to the state of Utah than an ambiguous mixture of ketchup and mayonnaise? Surprisingly, no. Fry sauce is much more than just a condiment to the people who consider it a beloved staple of Western American comfort food, says Kasey Christensen, the chief operating officer for Arctic Circle Restaurants — the fast food chain where it was invented.

For those who haven’t encountered what Christensen calls the "ultimate" dipping sauce, fry sauce is, at its most simple, an equal mix of ketchup and mayonnaise. With the same complexion as Japanese steakhouse "yum yum" sauce, fry sauce sets itself apart in its simplicity. Some may mistake fry sauce for Thousand Island, which is built on a mayonnaise base and a tangy flavor brought on by Tabasco, Worcestershire sauce, or chili spices, enhanced by a slew of minced pickles, onions, olives, and bell peppers. But fry sauce keeps it light with it's smooth consistency and rare incorporation of minced additives, as compared to Thousand Island, which is heavy and laden with ingredients.

I've always done this and didn't know it was a Western claim to fame until we went to SLC, Utah and it was everywhere. All the local places have their spin on it, but it's basically just mayo and ketchup.
