The highly popular and beloved egg noodles from the Swabia region of southwest Germany.
Traditionally Spätzle batter is quite thick because it was cut into noodles using the board & knife method. Even if using a Spätzle press or other method, thicker batter yields a better consistency. If you're using the Spätzle press yes, it will require some muscle strength - you don't want the batter to be so runny that it squishes right through with ease. That said, if you're straining way too hard to press the batter through, go ahead and add a bit more liquid to thin it out.
