I certainly agree with the whole culture thing
@KnittyNorah - Being a child of two immigrants, one from Belgium and one from Poland. I've certainly had plenty of first-hand experience of that.
Polish and German (my paternal grandmother's family were ethnic German) hospitality is *very* generous. I've had experience of Poland before and after the Iron Curtain came down, and certainly, after, the emphasis was that if you could afford it, you ate all the things that were once difficult to get under the communist system. Which basically meant a lot of meat (mainly in the form of hams and sausages) and a lot of sweet food. Added to the fact that Polish food does tend towards the stodgy at best...
Mum and I ruffled a fair few feathers when we pointed out the distinct lack of vegetable matter - we were told in no uncertain terms " but that's what poor people eat, and we're not poor"
The sausages and cakes were, admittedly, very nice, but our digestive systems certainly didn't appreciate it, and neither did our waistlines. Oh yes, and this was staying with the cousin of Red Velour Tracksuit fame... (that I mentioned up thread)
N.B. The diet under the communist system was heavily skewed towards dairy, vegetables and potatoes.
