  • 3 pounds seedless watermelon cubes
  • 1 cup coconut water
  • Juice from 1 lime
  • teaspoon sea salt


  • Crack open your watermelon, cut off the rind, and roughly chop it into cubes that are the same size. 
  • Throw the cubes into a blender and pour in the coconut water. Add the juice from one lime and a smidge of sea salt. (If your blender has less capacity than 64 ounces, you can divide the recipe and blend everything up in two batches.)
  • Blitz until liquefied. If your blender isn’t super powerful and you end up with some chunky pulp, just strain it out.
  • Chill it in the refrigerator, and then serve over ice. Or if you’re as impatient as I am, just pour it over ice and enjoy immediately.



You can store this summery beverage in a sealed container for up to 2 days in the refrigerator, but remember to shake the heck out of it or blend it again before serving.
