I quite like gefilte fish. I didn't grow up with it, but I was about 17 when I first tried it. The mother of a Russian mate of mine went out of her way to get carp (otherwise more or less a rubbish fish here) to make it. A bit of horseradish - especially that variety made with a bit of beetroot to make it red - and a matzo to put it on, and it is something I happily go back for more of.
