Flavours that shouldn't work

A while back I made this Goat cheese, prune and pistachio cake (although I'd call it a loaf) and the general reaction was - 'not sure about that'.  And recently I made this sweet chard tart and again wasn't that sure; the crunchy vegetables, boozy raisins and feeling that you were eating a Christmas mince pie made from vegetables was just a  bit strange - but I went back for seconds.

Anyone else got any recipes/memorable meals which really shouldn't work - but did.

I recently got a good book called the Flavour Thesaurus and was intrigued by some of the combinations it comes up with.
