- 4 cups peeled, seeded, and chopped watermelon
- 3/4 cup chopped cored fresh pineapple
- 2 cups light rum
- 1 cup Ginger Syrup
- 1/2 cup fresh lemon juice
- 4 cups ice cubes
- Small, thin watermelon wedges, about 2 inches, for garnish
- 2 1/2 cups sugar
- 1 1/4 cups water
- 1 cup thinly sliced peeled fresh ginger
Put the watermelon and pineapple in plastic containers and place in the freezer until completely frozen, at least 4 hours. Also, place the rum in the freezer for at least 4 hours.
Combine 2 cups of the watermelon, 1/4 cup plus 2 tablespoons of the pineapple, 1 cup rum, 1/2 cup Ginger Syrup, and 1/4 cup lemon juice in a blender. Blend on high speed until well combined. Add 2 cups ice and blend until smooth. Pour into a pitcher. Repeat with the remaining ingredients. Serve in margarita glasses or other wide-mouthed, stemmed glasses. Garnish with watermelon wedges.
GINGER SYRUP: Combine the ingredients in a large saucepan over low heat. Simmer for 10 minutes, remove from the heat, and allow to cool. Once cool, strain out the ginger. Makes about 2 cups.
