This type of sausage was culturally imported from Germany and popularized in the United States, where it became a working-class street food sold at hot dog stands and carts. The hot dog became closely associated with baseball and Americanculture. Hot dog preparation and condiments vary regionally in the US. Although particularly connected with New York City and New York City cuisine, the hot dog became ubiquitous throughout the US during the 20th century, and emerged as an important part of some regional cuisines (notably Chicago street cuisine ).
