Like Calvin below, I also skipped the egg white, and also switched up the rum, to Goslings in my case. A very good, wintery aperitif indeed. It starts off with lime tartness and a hint of sweetness, moves through rum molasses, and ends with mild bitterness. The spices from the allspice dram, amaro, and bitters support it throughout. An excellent pre-dinner drink on this cold January evening.
Wow. Out of light rum, used Bacardi gold; skipped the eggwhite (was out of eggs also). Simply awesome! Will be revisiting this one. Five stars and a heart!
Just made this, very nice and extremely dangerous iindeed, when separating one of the shakers one half flew over taking evrything that was on the bar with it, including a snow globe froma brewer I was cherishing lol
