The sausage can be eaten hot or cold, once cooked.
In 1980 a “Boudin Vert” sausage eaters association was formed, called the “Confrérie des Mougneus d’Vète Trëpe.” It is headquartered in Orp-Le-Petit, Belgium.
Each spring a Boudin Vert sausage festival is held in Orp-Le-Petit. Kale (which can grow all winter in Belgium) is harvested from the banks of the river called “Ry Fontaine”, and paraded through the streets.
“Boudin vert” means “green sausage.”
