Grown-Up Dipping Sauce

Jump to Recipe

About a year-and-a-half ago, we posted a recipe for crispy diner-style fries along with fry sauce, a species that seems to be indigenous to Utah/Southern Idaho. Being a born-and-bred Utah girl, of course I love my fry sauce. But this is the next step up–something you don’t have to apologize for or explain to people who may not be familiar with the pink stuff. This is full-blown grown-up fry sauce. And I can’t think of anything savory that it wouldn’t be good on.

Ingredient Notes

  • The Basics – Ketchup, mayonnaise, fresh garlic, red onion, and fresh lime juice are things you probably already have on hand. Fresh garlic and lime juice really do make a difference!
  • Creole Mustard – Don’t worry, you can find Creole mustard at most major American grocery stores (Zatarain’s is widely accessible and inexpensive). It is really uniquely flavorful and so good; if you’re looking for a great ground mustard, this is one of the best options. Walmart also makes a surprisingly good stone ground mustard.
  • Capers – If you are wondering (or ever have, or will now that I’m bringing it up) what capers are, they’re little buds from the caper bush, which grows in the Mediterranean. The buds are plucked off the bush before they can bloom and then they are pickled. They’re salty and mild and add a similar flavor to dill pickles, only a little more subtle and complex (hence the grown-up dipping sauce). If you can’t find capers, dill pickles would do in a pinch.
  • Cayenne Pepper – A little bit adds a kick of flavor without too much spice. If you’re worried about heat, start with a little less than a quarter teaspoon of cayenne pepper and then, after you’ve mixed everything together, add a little more until the sauce is as spicy as you’d like it.

Instructions

  1. Combine all the ingredients (some ketchup, mayo, capers, minced garlic, red onion, fresh lime juice, mustard, cayenne pepper, and salt) in your blender or in the small bowl of your food processor (if you have one) and blend until the desired consistency is reached.

  1. After you’ve mixed your sauce, store it in the refrigerator for at least an hour and up to a week. Serve it on whatever you want and prepare yourself for a little subtle finger-licking…

Frequently Asked Questions

  • Can I make this ahead of time? Yep. This dipping sauce is best when it’s had a chance to chill and allow the flavors to blend. Mix it up when you’d like and use it up within 7 days.
