In reply to andymac:
I'm working my way (rapidly) through a giant jar of Polish gherkins and some of their other food is great, not knowing what most of it is I simply buy and hope for the best usually great but they do like salt a bit too much for me.
I'll certainly give the mayo a try.
But best of all is some of their lumps of cheap, garlicky sausage, absolutely brilliant bait for fishing, chub and barbel love it and I always have some in the freezer.
