I am sure that I have violated some basic tenet of New Orleans drinking culture by bastardizing their classic cocktail, but damn, it tasted great! So send your zombies, I can handle them, especially with a few of these drinks to stiffen my resolve. The original drink really is a classic, and not just in New Orleans, where it is revered (Hurricanes are for getting drunk, and are completely forgettable). Unfortunately it is very difficult to make, although with a good basic recipe even the failures are pretty good. I started with this one, and it has been difficult to beat.
Anyway, Just replace the rye with a good rum — I have been using Mount Gay to good effect — and go a bit heavy with the bitters, and you will have an excellent start on a life of debauchery.
P.S. I checked around for other takes on this and was horrified to discover that most people call for white rum for this drink. Do not, on pain of being haunted by Santeria Priestesses for the rest of your life, use white rum. Tonight I am going to try Goslings, and tommy:eats has tried English Harbour Five year rum.
