Video: Making Fenway Franks
Hot dogs begin as large cuts of meat that go through a grinder, get blended with spices such as garlic, onion, and mustard, and then are cooled with a special process so the juiciness is preserved. The meat then gets stuffed into casings, twisted, and hung, and cooked in a smoker, chilled, and dried. The hot dogs are then shot through machines that remove casings, and as the franks move down the production line, inspectors pick off any imperfect ones before the hot dogs make it out of the factory.
