A criminally underrated tropical cocktail is the Saturn, a late 1960s recipe that includes several syrups along with Gin. I decided to riff on it using Rum instead of Gin, so I named it after one of Saturn’s many moons.
½ oz Lime Juice
½ oz Orgeat
½ oz Passion Fruit Syrup
¼ oz Falernum
1½ oz Rum
Shake with crushed ice and strain into a Coupe glass.
I tried this with the best White Rum around, Probitas. That rum is a mix of Barbados rum and Jamaican rum and is so delightful when you want to taste the rum in a cocktail of this style. I also tried this with Smith & Cross Jamaican rum, which is heavier than the Probitas but still not overpowering the rest of the ingredients. If you made this with each of the rums it probably would reinforce your style preference (I preferred the Jamaican) but both are excellent.
I really like the subtle flavor of the Falernum in this, and I think it pairs well with the Passion Fruit Syrup and the Orgeat.
Give it a try and let me know how you like it.
