• 2 ounces fresh lime juice (1/4 cup)
• 2 ounces orange juice (1/4 cup)
• 1 to 2 tablespoons simple syrup

Steps:

1. Mix frozen watermelon cubes, rum, lime juice, orange juice, and simple syrup in a blender until smooth. (Start with 1 tablespoon of simple syrup and add additional, to taste.) Stop to scrape the sides of the canister occasionally if not using a high speed blender.
