A long-time family favorite. The authentic stands use Vienna Beef franks and buns with poppy seeds and that trademark green relish and yellow mustard. If you're not fortunate enough to live near a stand (like us), this home version does nicely (with my own preferred changes of course)! The natural casing frankfurters have a pleasant "pop" when you bite them and are far superior to normal hot dogs. I don't advise using serranos in place of sport peppers as they are not the same type of chile and the serranos are MUCH hotter (as well as not usually being found pickled).
