Watermelon Granita Recipe

Ever tried turning something simple into a surprisingly bold summer treat? This watermelon granita feels bright, icy, and just a little rebellious. With its sharp chill and fresh fruit flavor, it’s not your usual quiet frozen dessert, it’s refreshing in the most unexpected way.

The natural sweetness of watermelon meets a hint of salt and a splash of lemon, creating a balance that feels clean, vibrant, and energising. It’s messy, honest, and wonderfully fuss-free, exactly the kind of cool-down you crave on long, sunny days.
