When you were younger, experimenting with condiments was just something you did. And if you mixed the ketchup with the mayonnaise, you probably realized that the end result was kinda-sorta incredible. This is the basis for “fry sauce,” reports Huffington Post, a sauce that a few different locations worldwide call their own.

While the Arctic Circle restaurant chain in Utah claims to have “invented” the sauce (which often includes some vinegar and Worcestershire sauce, as well as a dash of salt and pepper) those in Puerto Rico have been familiar with it for quite some time as well. For them, it’s more commonly called “mayo-ketchup,” and it’s an extremely important ingredient for foods like tostones, or fried plantains. While the exact origin might be a little fuzzy, one thing’s for sure — everyone enjoys this stuff.

Utah is such a fan of the stuff, that it’s actually packaged in certain restaurants.

And of course, Arctic Circle is so proud of it, that they have their own bottles available for patrons to use.

For those who love condiments, you might think that fry sauce is pretty similar to Thousand Island dressing. And while Thousand Island is also a darn good dipper, it’s definitely not as smooth or creamy as fry sauce. Besides fries, you can also dip your onion rings in there, or — well, anything, really.

Next time you grab some fries, try to create your own — chances are, it’s an experience you won’t forget.
