A simple mocktail with refreshing and sweet iced Watermelon Granita topped with sparking lime water Рor a flavor of your choice! Top with sparkling ros̬ for a spiked beverage!



  • 56 cups watermelon, cubed
  • 1/2 lemon, juiced
  • 1/2 cup granulated sugar
  • 3 cups ice, divided
  • 24 cans sparkling lime flavored water (or flavor of choice)


  1. In a blender, add watermelon, lemon juice, sugar, and 2 cups of ice. Blend until roughly combined (ice chunks are ok!). Add the remaining cup of ice and blend until smooth.
  2. Pour into a shallow pan (9×13 works great) and put in the freezer. After 30 minutes, take a fork and rake the mixture. Repeat after 1 hour, and again 30 minutes to an hour later. When ready, the mixture will be frozen like a slushy, but not solid.
  3. Scoop into a cup and top with your desired amount of sparking water for a refreshing mocktail! You can also enjoy the granita on its own like a sorbet.


Store watermelon granita in the freezer; it will harden up, so the next time you want to enjoy it, let it sit on the counter for a few minutes to soften up enough to serve it. Best if eaten when fresh.
