Heyo my names Hazel, find me on my socials with the links below. Heres a link to my current queue. A hot dog (also spelled hotdog) is a grilled or steamed sausage sandwich where the sausage is served in the slit of a partially sliced bun. It can also refer to the sausage itself. The sausage used is the wiener (Vienna sausage) or frankfurter (Frankfurter Würstchen, also just called frank). The names of these sausages also commonly refer to their assembled dish. Hot dog preparation and condiments vary regionally in the United States. Typical condiments include mustard, ketchup, mayonnaise, relish, and cheese sauce, and common garnishes include onions, sauerkraut, jalapeños, chili, grated cheese, coleslaw, bacon, and olives.
