A hot dog is a cooked sausage, traditionally made from beef, pork, or a combination of meats, served in a sliced soft bun and topped with a variety of condiments. It is one of the most iconic and widely consumed foods in American cuisine, closely associated with ballparks, backyard cookouts, and street food culture.
The hot dog has deep roots in German and central European sausage-making traditions brought to the United States by immigrants, and it became firmly embedded in American popular culture over the course of the late 19th and 20th centuries. It is especially associated with cities like Chicago and New York, each of which has its own strongly held traditions around toppings and preparation — Chicago style notably includes mustard, relish, onion, tomato, pickle, sport peppers, and celery salt, but explicitly no ketchup. Regional variations in bun style, sausage type, and condiments are significant and a matter of local pride across the country.
