A Wiener, also known as a hot dog, is a type of sausage that is typically made from finely ground meat, often beef or pork, mixed with spices and flavorings. It is usually encased in a thin, edible skin and is known for its smooth texture. Wieners are commonly served in a sliced bun and topped with condiments like mustard, ketchup, onions, and relish. The term "Wiener" originates from Vienna, Austria, where this style of sausage was first popularized. In the United States, hot dogs are a staple at barbecues, sporting events, and street vendors, making them a beloved part of American cuisine.
