Soak the rolls in milk for about 1 hour. Then stir with a fork until it becomes a paste. Now stir in the remaining ingredients. Add enough flour so that the fork stays in the dough. Then the right consistency is achieved.
In the meantime, bring a large saucepan of salted water to a boil. In portions, preferably with a large spoon, pour the dough into the boiling water. When the dumplings start to swim after approx. 10-15 minutes, they can be taken out and served with applesauce or morello cherries, for example.
