In principle, there is no fixed recipe for this dish - any preparation of hot sauerkraut with meat and potatoes could qualify - but in practice there are certain traditions, favourite recipes, and stereotypical garnishes that are more easily called choucroute garnie than others. Traditional recipes call for three types of sausage: Frankfurt sausages, Strasbourg sausages, and Montbéliard sausages. Fatty, inexpensive or salted cuts of pork also often form a part of choucroute garnie, including ham hocks, pork knuckles and shoulders, back bacon and slices of salt pork. Other recipes call for pieces of fish or goose meat, but this is far less typical.
