Jakarta Mai Tai
Shake all with ice and dump into a glass; garnish.
For the curry-leaf syrup: Dissolve 2 parts white sugar to 1 part water on heat. Take off heat and throw in curry leaves. Let steep 30 minutes and strain.
A riff on the Trader Vic's Mai Tai, inspired by realizing the nuttiness of curry-leaf syrup could be an orgeat substitute.

So glad you tried it and you liked it! The recipe is built quite directly on the modern version of the Trader Vic Mai Tai, including the nutty curry-leaf syrup in the place of orgeat and even the split rums.
Phenomenal drink, so this is nitpicking--but shouldn't this be a Jakarta Daiquiri? 2 oz. rum, 3/4 lime, 1/2 syrup is a pretty standard daiquiri, and adding a bit of Curacao isn't unheard of. Muddling 5 fresh curry leaves in cane syrup did the trick for me, and I strained onto new ice.
