In Southern Germany, Spätzle and Knöpfle aka. egg noodles are very popular and served quite often. Maybe I should narrow it down a bit – they are popular in Swabia and in Baden (where I am from). I would not dare to say they are super popular in Bavaria – they have their own favorites ;P However, I brought my fondness for this type of noodles to Berlin many years ago. We love to prepare dishes like these Swabian Knöpfle with Leek & Meat Sauce – among many other traditional dishes from the area.
