I like to experiment with foodstuffs and suppose I must combine a lot of things that others would consider weird. Nothing really springs to mind in that sense.
One thing I remember from childhood, however, is that I had a cousin whose favourite sandwich was comprised of strawberry jam and sliced pickled onions. As far as I remember, she used to eat this sandwich just about every day in life. Where she got the idea from, I've no idea and - funnily enough - I can't remember whether I ever tried the combination! :)
