Clean the leek, cut into rings and wash thoroughly. Heat 2 tablespoons of fat in a large pot. Add the leek and sauté for about 5 minutes while stirring. Sprinkle flour over the leek and sauté briefly.
Deglaze with wine, 3/4 litres of water and cream. Bring to the boil, stir in broth and simmer covered for about 15 minutes. Cut liver loaf and bread into pieces of about the same size. Put both alternately on the wooden skewers, leaving the ends of the skewers about 2 cm free.
Heat 1 tablespoon of fat in a frying pan. Fry the skewers all around in it for 3-4 minutes until golden brown. Add processed cheese to the soup and melt while stirring. Season soup with salt and pepper. Serve the soup.
Strip the meat loaf and bread directly from the skewers onto the soup or add to the soup.
