Add eggs and water gradually, stirring until you get a soft, sticky batter. The dough should be thicker than pancake batter but softer than pasta dough.
Bring a large pot of salted water to a boil.
Using a spaetzle maker, colander, or spoon, drop small pieces of dough into the boiling water.
Cook for 2–3 minutes, or until the dumplings float to the top.
Drain well and toss with butter if desired.
Serve warm alongside stews, paprikash, or goulash.
