Luxirare Blackberry Mojito (Park Hyatt Bar, Paris)

I love traditional mojitos but I've also had a fantastic blackberry mojito at the Park Hyatt bar in Paris. It isn't your most likely flavor combination (blackberries and lime ??) but it is really really delicious.
Recipe; rum, ravaged mint, whole mint leaves, lime juice+rind, club soda, powdered sugar or brown sugar, black salt, and blackberries
