Meanwhile, heat the olive oil in a frying pan with a lid and cook the Brandt & Levie sausage, covered, 6 - 8 minutes. Remove from the pan and keep under aluminum foil.
Meanwhile, finely chop the onion. Chop or press the garlic. Cut the leek in thin slices.
After you have removed the sausage from the pan, add half of the butter to the pan. Fry the onion and garlic for 2 minutes on low heat. Add the leek and celery, turn up the heat and stir-fry for 2 minutes. Deglaze with the bock, add the sausage (including moisture) and braise, covered, for 6 - 8 minutes on low heat. If necessary, remove the lid of the pan in the last 2 minutes to allow excess moisture to evaporate.
