So... I'm not gonna say I'm a better bartender than Sam MFing Ross, far from it... but this didn't speak to me.
Neither did the original, though it was a little bit closer.
Both were *almost there*, though. So I made it this way:
1 1/2 oz bourbon
3/4 oz aged Jamaican rum
1/2 oz Amontillado sherry
1/4 oz Carpano Antica
1 barspoon ginger syrup
with oils from lemon *and* orange expressed over the final product.
