For My Reference: Whisky Tropicale

I've never found a printed recipe for the cocktail that a bartender at the local restaurant Cactus used to do. Last time we were at Cactus, it was no longer on the menu. Anyway, I was reminded that I should at least write down my best guess at what goes in it so it doesn't go totally lost:

Whiskey Tropicale

Bourbon whiskey
bitters
lime juice
mango juice or mango blend
ground nutmeg

Shaken with crushed ice to blend, strained to serve. Why no, I don't have any proportions. I think I have generally used a mixed mango-passion fruit juice from Trader Joe's but keep meaning to try with straight mango from Looza. I'm pretty sure the original was not a blend juice but just straight mango. No idea what whiskey they used, but I've been happy using the Bulleit bourbon.
