Mix flour and salt in a large bowl.
Add water and eggs and stir the dough together. The amount of eggs you need depends on humidity and other factors, so start with 4 eggs and add more until you have a thick and smooth consistency.
Bring a large pot of salted water to a boil.
You now need to "shape" your spätzle from the dough, which can be done in the following two ways:
1. Press the dough through a spätzle press (the press resembles a very large garlic press). Hold the press over the pot with boiling water as you squeeze the dough through the press.
2. Spread the spätzle dough thinly on a cutting board. Tilt the cutting board over the pot with boiling water. Cut the dough into strips, letting them drop into the water as you cut.
Spätzle are cooked when they rise to the surface.
Place the finished spätzle in a heated dish as they are done.
Served, for example, as a side dish to a stew.
