Ingredients

  • 6 cups frozen cubed watermelon (seedless) see note below
  • 3 tablespoons fresh lime juice, or to taste plus sliced limes for garnish
  • Water as needed to thin it out

Instructions

  • Remove the cubed watermelon from the freezer, and let it sit on the counter for a few minutes so it's not so frozen. If the watermelon is too clumped together, break it up with a rolling pin.
  • In a blender, blend the frozen watermelon cubes with lime juice to taste. As it blends, add cold water as needed to thin it out. Use a spoon to loosen it up as needed.
  • Serve immediately. Garnish with lime slices or mint leaves (optional).

Notes

  • Freeze watermelon for at least 5-6 hours, or preferably overnight. It can be frozen for up to 2 months.
  • Freezing the watermelon: Lay the cubed watermelon flat on a single layer in the resealable bag. You can also flash-freeze the watermelon on a sheet pan and then transfer to the bag. This way, you won’t have a huge chunk of watermelon.
  • Need to add a sweetener? Watermelon is already naturally sweet, but if you need extra sweetness, try making a simple syrup at home. Simmer equal parts of granulated sugar and water in a small pot for a few seconds, until dissolved, stirring.
Substitutions and variations:
  • Lime juice: Fresh lemon juice
  • Water: Coconut water.
  • Add-ons: Strawberries, wine.
