Re: "I'm sure I heard passing references to Polish delicatessens"
@John Presland - "Dip in. There's some good stuff there. Try Krakowska sausage and Bryndza cheese."
I would offer my vote for the many large sausages that are fantastic on a BBQ, Keilbasa my favourite and the tray deserts are fantastic.
An aside - These were intorduced to me at a barbeque by a Polish friend and her Scottish boyfriend who had been living here for well over a decade, without her family (you know taking our working man's accountancy jobs ). It's something I love about living in modern Britian and I fear that this is something we are going to lose. Certainly I have many friends who are terrified that they will have to get married or fight to apply for a passport simply to cary on living and working here as before.
