Not entirely sold on the recipe's construction - it's grabbing a Havana 7 Year by default instead of a Jamaican which is a real shame. Local rum supplies vary with the weather, but I reacquainted myself using Myer's Rum, that Jamaican pot still rum bottled like it's still the 1800s in a squat square bottle that could just as easily have contained Snake Oil. Delicious. Cut right through all the dilution that limes and crushed ice could muster. Trader Vic was a genius.
