In a tall, narrow mixing bowl, beat the smooth butter with salt, nutmeg and pepper until frothy. Add eggs and flour and stir with the electric hand mixer for another 2 - 3 minutes until creamy. Bring the meat stock to the boil and remove it from the hob.
Cut off the butter and flour mixture with a teaspoon dipped in the hot broth. The dumplings in the broth stand for 10 minutes with the pot closed, but do not boil. Arrange the soup, sprinkle with chives.
Tip: Process the mixture for the dumplings as soon as possible, otherwise the dumplings will not become loose.
