What is Spaetzle? How is it cooked?
Spaetzle is basically a noodle. Throw together egg, flour and salt (maybe some water to thin it out) and force it through a mold. Anything with holes can be used as a mold (for instance, I've used my old metal colander and that would work fine). Once the dough is formed into little pieces (it doesn't usually hold together for long threads), put it in boiling water to cook for a few minutes and dress it to eat however you desire. 

Note: some people say Spaetzle is a noodle, some say a dumpling, I have no preference, I just call it tasty!
