ha, saw 5ml syrup and orgeat .. had to be Trader Vic ... forget the syrup, boost orgeat to 15ml if yu prefer a sweeter tiki cocktail. great drink ! cheers.
Unlike many of Trader Vic's tiki cocktails, this is nicely sour. Per all tiki cocktails, the citrus is the prime flavour. The orgeat adds a nice hint of almond. The bourbon is still evident, but does take the usual role of all the alcohol in a tiki cocktail.
A little too tart on the first few sips (mellowed as it sat) and I couldn't taste the bourbon. I would make this again and halve the lemon and orange juices.
