All carp bashers, you are deeply biased because you probably tried the fish from polluted rivers or lakes in your own countries and you imagine Polish carp is equally bad.
Not true about the biased part. The only carp I've eaten-or ever will eat-was on my first Wigilia in Poland. I ate, or at least tried, it baked, fried and in aspic. It was and always will be disgusting.
Fortunately my Polish fiancee doesn't like it either, so when I visit her in Germany we'll have salmon, prawns, and other edible dishes, but not crap-oops, I mean carp.
