Delicious! This is bound to become one of my alltime favourite summer drinks. I make it with Rum Fire from Hampden, an absolute top class Jamaican white overproof rum. Instinctively, I used to mix a Planter's punch with that rum that tastes quite similar to this drink, using orange juice, lemon juice, Angostura bitters and grenadine syrup. But this original Jamaican drink tastes a little more rounded and smoother.
