A corn dog is a hot dog or sausage coated in a thick cornmeal batter and deep-fried, typically served on a stick. Its exact origin is disputed: a cornmeal-battered hot dog on a stick was sold at Oregon's Pronto Pup stand in 1941, while the Fletcher brothers popularized the 'corny dog' at the Texas State Fair in 1942, a claim the fair still promotes today. The batter is a mixture of cornmeal, wheat flour, eggs, and milk, fried until crisp and golden while the sausage inside stays juicy. Corn dogs are a fixture of American fairs and carnivals, usually served with mustard or ketchup.
