Watermelon is the ultimate summer fruit, and it blends so perfectly with a bit of bubbly, gin or bourbon. These drinks are perfect to enjoy on a hot summer's day.
Place 1/2 cup watermelon at the bottom of each glass (1/4 cup each) and muddle with the back of a spoon. Fill cocktail shaker with ice and add 3 ounces bourbon, 1 ounce simple syrup, several dashes bitters, and shake. Pour on top of muddled watermelon and squeeze a quarter lime into each glass. Garnish with a lime wedge.
