For the broth, wash the meat, dab dry and dice roughly. Clean and wash all the vegetables and dice all but 1 carrot and 1 piece of leek. Put the vegetables, spices and meat in a pot.
Pour on 1 1/2 litres of water, mix everything and bring to the boil while stirring. Then let it stand at low heat for about 1 1/2 hours. Remove the meat and use it for other purposes (e.g. for a very spicy beef salad).
Pour the broth through a fine sieve. Meanwhile, for the semolina dumplings, stir butter until frothy. Alternately add semolina and eggs. Season with salt, pepper and nutmeg. Add parsley. Cut out dumplings with 2 wet spoons.
Pour into boiling salted water and let it simmer for 10-15 minutes at low heat. Cut remaining carrot and leek into thin, longish sticks and cook in the stock for 4-5 minutes. Drain the gnocchi and add.
