Soup greens clean or peel, wash and roughly dice half. Halve onion with skin. Wash the meat. Coarsely cut soup vegetables, onion, meat and 2 l water at medium heat slowly boil up.
Season with approx. 1 1⁄2 teaspoon salt, bay leaf, cloves and peppercorns and simmer open at low heat for approx. 2 hours. Skim off the resulting foam again and again.
For the spoon dumplings, mix flour, egg, 1 pinch of salt, nutmeg and 5-6 tablespoons of water with a wooden spoon. Let it swell for about 10 minutes. Then remove a small portion of the dough with the tip of each spoon using moistened tablespoons and slide it directly into boiling salt water.
Let the dumplings simmer for about 5 minutes. Lift out with a skimmer and let it drip off.
Cut the remaining soup vegetables into small pieces. Clean and wash the savoy cabbage and cut into strips from the stalk. Remove meat from the stock. Pour stock through a fine sieve into a pot and bring to the boil again. Cook the prepared soup vegetables and savoy cabbage in it for about 10 minutes.
Remove the meat from the bone and cut into bite-sized pieces. Add the meat and dumplings to the soup and briefly heat up again. Season soup with salt, pepper and nutmeg.
