How to make
Mix the brown sugar with the dark rum and stir until the crystals dissolve.
Put ice in a cocktail glass with a capacity of at least 14 fl oz (400 ml), by filling it with cubes halfway.
Pour the melted in rum sugar first and then vermouth, white rum and finally the carbonated drink.
Add slices of orange and decorate the cocktail with olives.
Serve it immediately with nuts or cheese of your choice.
The vermouth and rum cocktail is ready.
