Well, now I know it's kogel mogel and not gogel mogel. My grandfather used to recommend that for a sore throat. I always thought it was a Jewish thing. Is that a regular Polish food?
I actually think that it is. Is it popular in Pl? Hmm, hard to say. All my friends know what it is. Polishgirltx also seems to know it, so it can't be that unpopular. :)
