I haven't even touched on basic things like what is a pizza, and what goes on a hotdog. (Hint - if you put ketchup on a hotdog or skimp on the sauerkraut in some places, you're a heathen
Bah, sauerkraut. Nothin beats a New York System wiener. From the point the cook lines the dogs up on his bare, oddly hairless arm, to when they're topped with onions, brown mustard, and the "meat sauce" (a combination of finely grounded hamburger, celery salt, and other fat-based ingredients), they're the finest. If you're ever in Rhode Island (I'm not sure where else they're served... or allowed) try some out.
Do these even exist anywhere else? Or is the rest of the country/world actually slightly health conscious?
