Instructions
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.
Limeade
- 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.
- 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.
Serving
- Garnish with fresh watermelon, basil, and lime, and enjoy! Add a splash of your favorite liquor to upgrade to an adult cocktail.
Notes
- This recipe can be made with regular water instead of a CO2 charger if you don't have a soda dispenser.
- Fresh basil works best, but you can use other herbs like mint for variation.
- The basil syrup can be prepared ahead of time and stored in the refrigerator.
