Quite sweet and boozy, yet it is a well balanced drink and I liked it. I shaked with crush ice to have more dilution, added a dash of saline solution, and used Martin Miller Gin and Rhum agricole overproof. Great, but I will try next time with Jamaican overproof rum.
I didn't have any grenadine to hand, so increased the syrup to 10 ml and used 30 ml pineapple juice with non-wet ice.
This created a truly dangerous cocktail that I allowed the funk to shine with depth brought by the gin, all brought together with the pineapple. The head from the pineapple made it quite an attractive serve and I will certainly be making more of this riff as well as trying the original recipe when I have grenadine again.
