Very tasty.
(I've tried with 15 ml of Vecchio Amaro del Capo and 20 ml of dark rum (Havana Club 7 años) instead of gin).

A decent substitute for Green Chartreuse.

Thank you Simon - I'm looking forward to your Mono Blanco!
(Meanwhile I'm still trying to get a bottle of Fresh Monkey in Switzerland/Germany)

Mono Dorado translates to ,golden monkey'
(perhaps the white monkey made golden in this recipe?).
