I take my own syrup, ketchup, and mustard, just in case of emergencies, in my suitcase. Whatever I can steal from the hotels. It's usually Heinz ketchup, and they give you a weird mustard. You don't get French's or anything; you get some sort of Dijon or some mustard. That's just for hot dogs. I don't use mustard for anything else.
