Cook the beef until tender, remove it from the broth and cut into bite-sized pieces.
Simmer the finely chopped kohlrabi and the sliced carrots in the meat stock for approx. 10-15 minutes.
Knead the flour with the eggs, salt and a little water until the dough comes off the spoon and cracks, possibly add a little more flour. Put the batter into the simmering soup with a teaspoon, when the sparrows rise in the soup, they are done.
Before serving, season again to taste, add the beef cubes and sprinkle the finely chopped kohlrabi leaves or chopped parsley into the soup.
