Crawfish boudin is a specialty of Cajun cuisine, a sausage that is traditionally prepared with freshly chopped crawfish meat and sautéed finely cut vegetables such as onions, celery, green onion tops, bell peppers, garlic, and parsley.
The crawfish mixture is then combined with cooked white rice before being stuffed into natural casings. If no casings are available, the sausage mixture can alternatively be shaped into balls which are then dredged in breadcrumbs and fried. Typical seasonings include red pepper or cayenne pepper, salt, and white pepper or black pepper.
