Most recipes for hot dogs combine together a tasty blend of favorite meats (pork, beef, chicken, or turkey), meat fat, a cereal filler which could be either bread crumbs, flour, or oatmeal, a little bit of egg white, and a mouth-watering array of herbs and seasonings including garlic, pepper, ground mustard, nutmeg, salt, and onion.
Once these ingredients are grinded together, the stuffing is squeezed into sausage casings. Many of the hot dogs sold in stores are enclosed in synthetic cellulose casings, but most home-made hot dogs are made out of natural animal intestines.
