What is "hot dog"?

A hot dog is a cooked sausage typically made from a blend of beef, pork, or a combination of both meats. The mixture is seasoned with spices such as salt, pepper, garlic, and paprika, and encased in a thin, edible casing. Hot dogs are traditionally served in a soft bun and are often topped with condiments such as mustard, ketchup, onions, relish, or sauerkraut. They are a popular street food and are also enjoyed at picnics, barbecues, sporting events, and other casual gatherings.
