Boil water: Bring a large pot of salted water to a boil.
Make batter: In a bowl, mix flour and salt. Add eggs and half the water. Stir, adding more water gradually, until you get a thick, sticky batter (softer than pasta dough).
Form dumplings: Using a spaetzle maker, colander, or spoon, press small portions of batter into the boiling water.
Cook: Dumplings will sink, then float. Once they float (about 2–3 minutes), cook 1 more minute.
Drain: Remove with a slotted spoon and rinse briefly with warm water to prevent sticking.
Serve: Toss with butter or add directly to dishes like chicken paprikash.
