For the dumpling dough, mix toast or dumpling bread with water and milk and allow to soften briefly.
Add flour as well as salt and possibly yolk and work into a smooth dough. If the dough still sticks too much, firm it up with a little flour.
Cover with plastic wrap and let rest for about 20 minutes.
Form dough into a roll, cut off small pieces of dough and wrap any slightly frozen dumplings with them.
Cook in salted water for about 10 to 15 minutes, depending on size.
