  • 2 cups watermelon chunks
  • 8 large basil leaves
  • ½ cup sugar
  • ½ cup water
  • ½ cup lime juice about 4 to 5 limes
  • 1 cup cold water


  • Make the basil syrup. Combine the sugar, water, and basil in a small saucepan. Bring to just a boil, remove from heat and let cool for 5 minutes. Remove the basil leaves before using.
  • Purée the watermelon. In a blender, food processor, or with a hand blender, purée the watermelon until smooth. Strain through a fine-mesh strainer. You should have about 1 cup of watermelon juice after straining.
  • Make the limeade. In a pitcher or pan, whisk together the watermelon juice, basil syrup, lime juice, and water. Transfer to a soda or whipped cream dispenser. Screw the lid and nozzle on tight, and add a fresh CO2 charger to the container. If you don't have a dispenser, substitute soda water for regular water.
  • Serve. Garnish with fresh watermelon, basil, and lime, and enjoy! Add a splash of your favorite liquor to upgrade to an adult cocktail.


  • Canned soda water can be substituted if you don't have a soda or whipped cream dispenser.  Use about ¾ of the can and test before adding the whole can.
  • A soda or whipped cream dispenser will work.  A soda dispenser is a little more mess proof, the whipped cream dispenser will need to be tilted upside down and the nozzle placed well into the glass.
  • If your kids aren't a big fan of bubbles, they can be skipped!  The CO2 infusion makes it just a bit fizzy though and my kids (who don't like bubble water) love these.
