If you like watermelon, you'll love this punch. It's a cool and refreshing drink that will complement any summer gathering. I love making a double batch and serving it in a punch bowl with watermelon wedges and fresh mint.
Combine 1 cup of water with 1 cup of granulated sugar and a sprig of fresh mint in a sauce pan. Bring to a simmer over medium heat and stir until the sugar has dissolved. Simmer for 2-3 minutes and turn the heat off. Allow syrup to cool at room temperature. Remove mint spring before adding the simple syrup to the punch.
Cube watermelon fruit and blend in a blender until smooth. Strain to remove any pulp and add to a large container where you'll mix the punch.
Add coconut rum, pineapple juice, lemon juice, lime juice, orange liquor and mint simple syrup. Refrigerate overnight for best results or at least a 4 hours before serving to allow the flavors to marry. Just before serving, add about 4 cups of ice cubes to the punch bowl, add the punch and garnish.
Make some fun ice cubes out of watermelon juice and mint leaves instead of regular ice cubes. As the juice melts, it won't water down the punch and it's visually beautiful.
Sprinkle a little rum over the watermelon wedges and pop in the freezer 30 minutes before adding it to the punch. The cold, spiked watermelon makes the perfect adult garnish on a hot summer day.
