1 oz. (30 ml) aged rum
3/4 oz. (22.5 ml) simple syrup (1:1 – sugar:water)

How it's done
Add all ingredients into a shaking tin and dry shake (without ice) for roughly 10 seconds.
Add ice to the shaking tin and shake for another 10-20 seconds.
Double strain into an ice-filled lowball or pre-cooled stemware glass and let it sit for a few seconds to let the foam settle.
