Satan's Whiskers Cocktail
This recipe was found in Imbibe Magazine. The mix of flavors in this cocktail make it a pleasant though potent cocktail. Perhaps that is how it got its scary name. It is also taller than most neat drinks, so a larger glass is needed. According to A.J. Rathburn's Good Spirits book if you were to skip the Grand Marnier for another orange liqueur like curacao the drink would then be called a "Curled Satan's Whiskers."
