The Blackberry Mint Martini isn’t anywhere close to a real martini, since it features rum as its only alcohol. The blackberry and mint flavors are infused into it, and a touch of lime juice and simple syrup are the only mixers.
Rum is so often mixed with tropical fruits, so this drink makes an interesting departure from that. I like this one best when I can get blackberries have a tangy edge.
Put 4 blackberries and three shredded mint sprigs in a shaker and muddle. Add ice, rum, lime juice and the simple syrup to the shaker and shake vigorously. Strain into the cocktail class and garnish with the last blackberry and mint sprig.
