Join in a French tradition on Sunday, March 5th, at J&M Bar in Belleville for a Boudin Dinner from 1:00 p.m.-5:00 p.m. What is Boudin? Boudin is one of most unique, tasty and distinctly uncorrupted regional specialties in America. Basically, Boudin is a combination of cabbage, onions, cracklins, milk, flour, pork blood, salt, pepper and summer savory, or senti bon, which means “smells good” in colloquial French. Each recipe is slightly different.
