There was a good documentary on Channel 4 a while ago called something like "Bradford, city of Dreams". One of the people featured was a polish man was was an accounts manager when he lived in Poland but came from a family of butchers. He prepared meat in a traditional Polish style at his own butchers/smoke house in Bradford and sold locally. They looked awesome. Like everything there's differing levels of quality with all foods.
Some of the supermarket bought Polish sweets I tried a few years ago were pretty awesome. I think I've just contradicted my on point on quality.
