If the name isn’t descriptive enough then just think of a Whiskey Cocktail but better. I’m just kidding, this is actually very different than the normal Whiskey Cocktail. While the normal one is cardamom-y and kinda has a spice to it, this one is orangey and licorice flavored.
This first appeared in Jerry Thomas’s 1880 edition of his bartenders guide. His improved cocktail versions never really enjoyed the fame the normal ones enjoyed but they are very good and worthy of being remembered.
