Clean the pointed cabbage and cut into fine strips. Peel and cut the potatoes into eighths. Roughly dice the onions and garlic.
Let the olive oil get hot in a large saucepan. Sweat the onions and diced ham in it, add the garlic a little later. Also add the pointed cabbage and the potatoes and cook for a good 10 minutes until the cabbage has boiled down by about half.
Deglaze with the vegetable stock and cook very soft for a good 45 minutes. Season to taste with salt, pepper and nutmeg. Just before serving, add a dash of cream. Mettwürstchen or Kasseler go well with it.
