Like its Kentucky Derby cousin, this julep is quite a cocktail.
| 1 pint fresh blackberries, rinsed and dried | Crushed ice | |
| 8 tablespoons superfine sugar | 1 cup bourbon | |
| 1/2 teaspoon pure vanilla extract | Cold club soda | |
| 1 big bunch mint leaves |
Mash together the blackberries, sugar and vanilla extract 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 and discard the seeds.
Place 1 1/2 tablespoons of the blackberry liquid into a mint julep glass, add 8 mint leaves and muddle together. Fill with crushed ice, 1/4 cup of bourbon and a splash of club soda. Garnish with sprigs of mint. Repeat to make 4 drinks.
