Because of the high water content, I thought that watermelon would be best served as a granita! What is a granita??? Short and sweet, a granita is an icy, sweet treat usually made from fruit juices, coffee or wine. What sets this apart from a sorbet is that granita has a coarse texture to it instead of being spun into a silky smooth frozen treat. The coarse texture is achieved by occasionally stirring the mixture while it’s freezing.
