Finely grind the fried onions with a multi-chopper.
Mix the flour, eggs, salt, the ground onion powder, nutmeg and water into a spaetzle dough. The dough should tear off the spoon. Let rest for 30 minutes.
In the meantime, bring a saucepan of salted water to a boil. Cook and strain the spaetzle in several stages with the spaetzle maker or the spaetzle press. The spaetzle are ready when they swim high.
Either serve hot or warm up in a pan fried in butter.
