2 teaspoons (6 g) sugar
8–10 mint leaves
2 tablespoons (30 ml) lime juice
8 ice cubes
1 1/2 ounces white rum
2 ounces (60 ml) cold espresso or strong coffee
1. Moisten the rim of a chilled tall clear glass with a wedge of lime and dip the wet rim into a small flat dish of sugar. Rotate gently to evenly coat the glass rim.
2. Place the fresh mint leaves and lime juice in the sugar left on the dish. Lightly crush the mint leaves with the back of a spoon, and place the entire mint mixture in the prepared glass.
3. Place the ice cubes in the glass and add the white rum and espresso.
4. Fill the rest of the glass with club soda and stir well. Garnish with a lime wedge or sprigs of mint.
