OK, Are there any fry sauce fans out there? If you are in Utah you may really love fry sauce.
There is the usual recipe of ketchup and mayo. That is so bland and crappy I do have to say.
I like to dump and stir and you may adjust this recipe because home cooking is all about making it how "YOU" like it.
My basic recipe starts with this. 1/2 cup mayo, 1/4 cup ketchup, 1/8 cup mustard, 1Tbsp Dill pickle juice.
Now depending on what is at the house I will add some other things. Few dashes of Worcestershire sauce. Maybe some hot sauce, Horseradish sauce. Paprika. Dave's insanity sauce is my favorite but only a small 1/4 - 1/2 tsp or even less. That crap will burn your face off. What ever you like.
Like I said I love dump and stir. Make sure you mix it well. Serve with home cut fries. Or keep some around when you bring home the fast food.
Enjoy, and let me know if this helps. If you are not familiar with Fry sauce then give it a go. This is possibly the most popular condiment for fries in Utah and southern Idaho. It's a Mormon thing.
Arctic Circle serves it at most of its restaurants, and is credited with its creation.
