Fry Sauce is mostly a Utah thing, and I think that anyone who has not tried it, is totally missing out. It is one of my favorite foods ever. Fries are good, but it's just something you use to get to the fry sauce. Most fry-sauces are made with half mayo; half ketchup. That's okay, but if you truly want to enjoy the fry-sauce experience, follow the recipe below. It's really tricky, so I hope you don't mess up:
2 parts Mayo
1 part Ketchup
1 part BBQ sauce
You think you got it? If you run out of fries, it's okay to use your finger.
