The hot dog (also spelled hotdog) or dog is a grilled or steamed link-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 (also frank). The names of these sausages also commonly refer to their assembled sandwiches. Hot dog preparation and condiments vary regionally in the US. Typical condiments include mustard, ketchup, mayonnaise, relish, and cheese sauce, and common garnishes include onions, sauerkraut, jalapeños, chili, grated cheese, coleslaw, and olives. Hot dog variants include the corn dog and pigs in a blanket. The hot dog’s cultural traditions include the Nathan’s Hot Dog Eating Contest and the Oscar Mayer Wienermobile.
