It is a traditional recipe of andouille, a large smoked and boiled French sausage of pork intestine meat, close to the andouille de Vire, which with the andouille de Guémené are the two main types of andouille.
The andouille de Baye comes in two varieties, the traditional one and one that replaces some of the intestine meat with bacon.
Note that the French andouille is totally different from the Cajun andouille, which is a small non-smoked sausage that usually does not contain offal meat such as intestine. The French andouille is a gastronomic specialty very sought after and the traditional recipes are the most expensive types of sausages in France, together with the Morteau smoked sausage.
