Once the first unit is processed, dip the kitchen knife into the boiling water, spread the dough with the water on the board towards the back so that the layer of dough is very thin. The narrow end of the board also comes into the water from time to time, so that the sparrows slide well. Cook the sparrows in batches in the boiling water. As soon as they rise to the surface, they are done. Remove with a slotted spoon and rinse briefly under cold running water to prevent them from sticking together.
