For an original, thirst-quenching take on the original, try this watermelon-flavored beauty: Cut 1 slice of watermelon into cubes, remove the seeds and blend. Crush 6 mint leaves with 1/2 sliced lemon. Pour in a glass, add the blended watermelon, 1 2/3 ounces of rum and a bit of sparkling water. Add some crushed ice and garnish your glass with a piece of watermelon.
