　The sausages used in hot dogs are typically either boiled or steamed, or grilled on a grill grate or griddle. In stores and stalls, rotating grills with warming functions are often used. As for the bread, it can vary from being used at room temperature to being toasted or steamed, depending on the preference of the establishment or individual.
　The basic seasoning is mustard, and depending on preference, tomato ketchup, finely chopped relish made from onions and pickles, sauerkraut, and others are used. There are various variations such as chili dogs topped with chili meat, Chicago dogs with melted cheddar cheese, or sandwiches with vegetables like tomatoes, as well as salsa dogs topped with salsa.
　The idea of serving a hot sausage sandwiched in bread is believed to have been brought by immigrants from Germany. There is also a legend that a vendor who lent gloves to customers to hold the sausage was puzzled when they took them away, and as an alternative, came up with the idea of putting it in bread. There are various theories about who introduced this style that became popular in the United States, including Charles Feltman, who opened a stall in Coney Island (Nathan's, which was started by Feltman's employee Nathan), and Harry Stevens, a vendor at the Polo Grounds, but it is not certain. In any case, it is certain that such food in this form was recognized and sold in various places in New York in the late 19th century.
