I can't remember who told me that you should put pepper on your strawberries instead of icing sugar, but they were right. It seems like an odd combination, and when I first heard I thought it was wrong. But the ground pepper enhances the sweetness of the strawberries without overpowering the strawberry flavour. I'm not exactly sure why this is. I tried to google it, but no one could tell me (if you know why, I'd love for you to share!). You can't taste the pepper, exactly, it just does something amazing to the strawberries that you wouldn't expect.
Oh, if you want a list of other (somewhat) suprising food combinations, you could check out this list that someone has put together on Listverse.
