This is my new favorite drink. I had been in love with watermelon margaritas for years, but this summer I decided it was time to change it up. A Southern boy at heart, I always have bourbon on hand so this seemed like a perfect fit. Macerating the bourbon with lemon slices is a key step. Watermelon juice can be easily made by cutting watermelon into chunks and squeezing through a kitchen towel. —Chef James
Place a bottle of bourbon in the freezer to chill thoroughly, several hours to overnight. Fill a glass pitcher with 2 lemons, thinly sliced. Pour in the chilled bourbon and let them get to know each other while you prepare the remaining ingredients.
Fill a cocktail shaker half way with ice, pour in the bourbon and watermelon juice. Shake vigorously to chill. Pour into a highball glass filled with ice and top with a splash of ginger ale.
