Fantastic name aside, this is a spectacular cocktail and Broken Down Doll's most recent predilection. Quite possibly due to another of my favourite ingredients being featured. It shouldn't be much of a challenge to guess which one that is...and, O, three dashes is my preferred measure.
Recipe and cautionary caveat compliments of The Savoy Cocktail Book by Harry Craddock. I too suggest stopping at three. Three and a half tops.
