1 1/4 cups fresh blackberries, plus more for garnish
1/4 cup superfine sugar
1/2 teaspoon vanilla extract
1 cup + 4 tablespoons bourbon
1 bunch of fresh mint leaves, plus whole sprigs for garnish
shaved or crushed ice
club soda, chilled
1. Mash together the blackberries, sugar, and vanilla in a small bowl and let macerate at room temperature until juicy, about 20 minutes. Strain the mixture through a sieve into a bowl, pressing against the solids with a rubber spatula to extract as much juice as possible. Discard the seeds.
2. Put about 2 tablespoons of the blackberry liquid and 1 tablespoon of the bourbon into a silver mint julep cup.
Add 8 mint leaves, and muddle together.
3. Add shaved ice until the cup is half full. Insert a sprig of mint and then pack in more ice to about 1 inch over the top of the cup. Pour 1/4 cup bourbon over the ice. Add a splash of club soda, and garnish with several mint sprigs and blackberries.
4. Repeat steps 2 and 3 to make 4 drinks.
Serve & Enjoy!
