  • Blender
  • Fine mesh strainer


  • 4 cups watermelon cubes
  • ½ cup lemon juice
  • 3 cups water
  • 6 tbsp sugar or a little more/less to taste
  • mint for garnish
  • ice to serve


  • Put 4 cups watermelon cubes in a blender and blend until smooth.
  • Add ½ cup lemon juice, 3 cups water, and 6 tablespoons sugar, and blend so they are well mixed.
  • Pour through a fine mesh strainer to hold back excess pulp and seeds.
  • Chill until needed, then serve over ice, garnished with some mint.


  1. Adjust the amount of sugar to your taste, and depending on how sweet your watermelon is.
  2. You can use fresh or bottled lemon juice, though I always recommend using fresh. Check the post for detailed instructions on how to peel and juice a lemon.
  3. Tip: Use seedless watermelon!
