Ok, it’s light rum instead of dark rum, but with otherwise identical ingredients, albeit in fractionally different quantities, this is so similar to a Mai Tai I don’t think it qualifies to be called anything else. At least I know I’ll like it however, the Mai Tai’s a fabulous drink.
A Mai Tai must always be made with aged gold or dark rum. Like other tiki drinks, many of them originally used white rum as it was easier to get than the darker rums.
