A hot dog is a food consisting of a grilled or steamed sausage served in the slit of a partially sliced bun. It can also refer to the sausage itself. The sausage used is a wiener or a frankfurter. The names of these sausages also commonly refer to their assembled dish. Hot dog preparation and condiments vary worldwide. Typical condiments include mustard, ketchup, mayonnaise, relish, and cheese sauce, and common garnishes include onions, sauerkraut, jalapeños, chili, grated cheese, coleslaw, bacon, 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.
