We are big rum drinkers and have original tiki recipes back to the 1950s. This was great. Loved the name as I also am a big fan of Jamaican rums. Used a Jamaican Blond rum and halved the Grenadine (as I do not like my drinks too sweet). Also did a float of Overproof Navy rum as I felt it was missing a little of the rum flavour. Will do this one again over the summer.
I topped up about 35ml of lime juice with 10ml of lemon juice and replaced the passion fruit juice with passion fruit liqueur to about 30ml.
It feels right, not too sweet but slight tang, coconut rum goes well with the orange and cranberry and it feels quite premium.
I might need to test this on some people
