Intoxicologist Erick Donoghue put together:
Bacardi White Rum
Malibu Coconut Rum
Put all parts in shaker with ice...shake the fucking shit out of it. (Pineapple Juice has the tendency to get frothy when shaken so serve it up in a collins or a big wine goblet like I did)
Do it right and a really cool almost neon green color will result.
Garnish with Pineapple wedge, absolutly incredible, everyone loves it. Really boozy too!
