The sausage is eaten raw or stewed, which gives it a spreadable consistency once broken from its casing. In winter it is also served with Grünkohl (kale).
The name Bregenwurst comes from the Low German word Bregen (or Brägen) meaning "brain" .Adelung - Grammatisch-kritisches Wörterbuch der Hochdeutschen Mundart - Der Bregen: lexika.digitale-sammlungen.de
