For the egg dumplings, bring lightly salted water to a boil in a large pot. Mix the flour together with the eggs, milk and soft herb butter and spices to taste in a bowl with whisk.
Sift through a spatula sieve into the water and wait until they float to the surface. Drain the water and fry the dumplings together with the 3 eggs in a pot with a little oil.
Serve with the cress.
