Turn your watermelon into a cocktail keg. Cut the lid from the top and scoop out the fruit. Drill a small hole near the bottom and then use a knife to widen the hole until it's slightly smaller than a keg shank. Attach the shank, then fill the melon with a delicious and refreshing watermelon sour. To find a keg shank, look for the kit at kegworks.com ($30).
It takes about 10 minutes to make the watermelon sours. Puree 4 cups watermelon chunks; strain. Stir in 4 ounces Alize Red Passion or other fruit-flavored liqueur, 8 ounces gin and 2 cups sour mix; chill. Add sparkling rose before serving. Garnish with lime. Makes 10 to 12 drinks.
