The only consistent ingredients are the Goslings Black Seal Rum (defines it as a truely Bermudian drink), another light rum (Originally a Barbados rum), and orange and pineapple juices - with most opting for falernum over a basic sugar syrup. The rest is up to the drinkers personal favourites, personally I like Grenadine and cherry juice in mine to add some deeeper colour, and stronger flavours allowing for more Goslings to be added without noticing a change in strength.
