Frankfurters are a type of sausage that originated in Frankfurt, Germany. They are typically made from finely ground meat, often a mix of pork and beef, and are seasoned with various spices. Frankfurters are usually encased in a thin, edible skin and are known for their smooth texture and mild flavor. These sausages are commonly served in a bun and are popular at outdoor events, such as barbecues and sporting events. In the United States, they are often referred to as hot dogs and can be topped with condiments like mustard, ketchup, and relish.
