This cocktail is named after a famous incident involving General Patton in Italy during WWII. Like the controversial leader, the drink is crisp, strong, and gets the job done.
Stir together whiskey, lime juice, Fernet-Branca, sorghum syrup, and Faretti Biscotti Famosi in a 10-oz. glass. Add ice cubes, and top with tonic water. Stir in sea salt and cracked pepper.
