Boudin is a sausage that shares many of the same ingredients as Dirty Rice. Boudin is unique among South Louisiana sausages because it contains pork and organ meat, cooked down in Cajun seasonings and spices, mixed with cooked rice before stuffing into sausage casings. Although the ingredients are cooked before being stuffed into the casing, Boudin is usually steamed before serving, but it is also common to find grilled boudin and smoked boudin.
