This recipe is adapted from Imbibe!: From Absinthe Cocktail to Whiskey Smash, a Salute in Stories and Drinks to "Professor" Jerry Thomas, Pioneer of the American Bar (Perigee, 2007) by David Wondrich. The "Professor" Jerry Thomas himself once called this drink "a capital punch for a cold night." We couldn't agree more.
