I don't eat it on hot dogs or burgers or anything. But I like it in my potato salad and used as an ingredient in cooking. But not as a condiment. Its required to be in potato salad, or its not a good potato salad.
This is also acceptable. I've had food that has mustard as an ingredient, properly mixed in with a bunch of other stuff, and that's fine. But anyone in this thread who puts mustard on like, a hot dog or a burger or a sandwich? You're monsters, all of you.
I put mustard, ketchup and mayonnaise and just about every hamburger I eat. Putting the mustard on separately makes me a monster, but what if I were to pre-mix the condiments into one mega condiment that I'm going to call Ketchotard™ or Kustarnaise™ and then add it to my burger? Am I still a monster?
