Blackberry Mint Julep is a twist on a classic. Bourbon, simple syrup, mint leaves, club soda, and blackberries. It's very important to have finely crushed ice.
Put the blueberries and mint into a julep cup, double old fashioned glass or a collins glass and muddle. Pour the simple syrup and muddle a bit more. Add the bourbon, club soda and top with the finely crushed ice. Stir until the cup becomes frosty
