Cook the smoked pork in salted water for about 2 hours.
Peel the vegetables, chop them roughly, cook in salted water (not too much) for half an hour. Puree the vegetables with a hand blender to a pulp. There may also be bits left. Season with chicken stock, possibly smoked pork stock, salt and pepper.
Cut the Kassler into large, bite-sized chunks and add to the soup.
