Bursting with sweet watermelon and bright, tangy lime, this granita is a cool, refreshing dessert that requires no ice cream machine or churning. With only three ingredients, it's an easy treat to whip up in the summer heat. Granita is a simple italian dessert, originating from sicily. It's made with sugar, water, and some kind of fruit. You'll love this dessert if you like sorbet or italian ice. It's very similar to both of those treats but has more texture. The unique way it's created makes it seem like you are eating frozen fruity crystals. We garnished it with fresh basil for a little herbaceous pop, but you can zest a lime or just serve it straight up. The watermelon granita also makes a great base for frosty cocktails. After grating the granita and adding it to your glass, pour on a shot of rum, tequila, or vodka for a thirst-quenching adult beverage.
