Ingredients:
  • 8 cups seeded, cubed watermelon (about 4 pounds)
  • 1 1/3 cups light rum
  • 1 ½ cups freshly squeezed orange juice, or more to taste
  • ½ cup orange liqueur
  • ¼ cup powdered sugar, or more to taste
  • 2 ounces freshly squeezed lime juice

Directions:

1. Put the watermelon cubes in a plastic freezer bag: freeze for at least 8 hours.

2. Purée the watermelon and the remaining ingredients in batches in a blender or food processor until smooth, scraping down the sides occasionally.  Combine the processed mixture well.

3. Serve in a large old pickle jar or a punch bowl and scoop the mixture into Mason jars, tin cups, or other festive glasses.
