I would even argue to call "sauerkraut" a dish. You don't eat it only by itself. BTW, I prefer the name kapusta kiszona (kapoosta kishona) or sour cabbage, because just like FISZ said, it's not a German "invention".
What I wasn't aware is that it was originally Chinese. I only knew that it was brought to Poland and the rest of the Eastern Europe by some Asian tribes, probably Mongols, at the beginning of the Middle Ages, and it was used by polish cooks ever since. Interesting. Every day you get to know something new.
They keep trying to convince me that polish food can be good.
Well, you can't please them all. Personally I love Bigos and sour cabbage. Besides, it’s very healthy. :)
Compare it to Hispanic Thai Indian French Malaysian Italian English Chinese Japanease and almost any other country and can you really tell me that there is anything good about Polish food.
Well aside from "plinze" and "ogórkowa" soup I love it all.
PS: This conversation is rather pointless, as everybody has different taste, and one really can't say which one is better or more valuable.
