I have to say that if I had to choose one fruit that goes well with vanilla beans it would be pineapple.
Pineapple is wonderful by itself but it really takes on that Enchanting quality when you marry it with vanilla.
Try Grilling pineapple slices and topping with vanilla sugar, or a fresh vanilla syrup and garnish with part of the vanilla pod, and fresh mint.
I get asked this all the time about BBqing fruit. You simply put it on the grill
and bbq it. Heat it up basically. it brings the sugars out in the fruit, and caramelizes it a bit. Works the same with peaches and pears.
