The Zombie was created in the 1930’s by Donn Beach AKA Don the Beachcomber. As with many tiki drinks, the Zombie is not short on flavor, rum, and recipe variations.
Don was so protective over his recipes, that he wrote them in code- even his bartenders didn’t entirely know his formulations. He would premix elements and number the bottles, so a bartender may add a 1/2 oz. of “Don’s Mix Number 4” instead of the individual ingredients. While many of his recipes disappeared with his passing in 1989, bartenders, mixologists, and cocktail enthusiasts haven’t stopped attempts to crack the cocktail code.
Full disclosure: I have some history with the Cosmopolitan. As a college student in the late 90’s who watched Sex and the City, the Cosmo was my drink of choice. In those days, I was usually drinking them out of a plastic cup at my college dive bar.
(I wasn’t very picky. Or very classy.)
When my friends and I were feeling fancy, we would go to the restaurant in town that served them in a martini glass.
