The three most popular ways to cook hot dogs is in either a steamer, rotisserie or on a roller grill. Hot dog machines are a popular item for schools, concession stands, snack bars, festivals and fairs. Roller grills use heating elements inside each roller to heat and maintain the desired temperature. Rotisseries are enclosed within a rotisserie that holds the hot dog and passes under a fixed heating element. Steamers are totally enclosed and cook by using steam that is generated from a well under the holding area.
