Aussie vegimite and white chocolate. The vegimite kind of caramilises and the sweet from white choc mixes well with the saltiness from the vegimite. We did them for Australia day and ANZAC day. Very yummy.
Oh, and I can think of another one: Once a friend of mine gave me Ouzo-chili-chocolate as a present. Maybe from Greece? I don't remember it. The only thing I remember is that it tasted way better than it sounds ;)
This combo actually makes sense to me. The ouzo is kind of licorice-fennel flavor and the hot chili. I've occasionally eaten a bar from Vice chocolates in California that's 65% cocoa and is topped with dried figs and fennel seeds. I'd like it a little higher in cocoa content but I'm quibbling. Very good.
