The Hanky-Panky is a cocktail made from gin, sweet vermouth, and Fernet-Branca, an Italian digestivo which is the star of this recipe. It was created by Ada Coleman, head bartender at the Savoy Hotel, London somewhere between 1903 and 1923. It was served initially to Sir Charles Henry Hawtrey (1858 to 1923), an actor and writer.
Add the gin, sweet vermouth and Fernet-Branca into a mixing glass with ice and stir until well-chilled.
Strain into a chilled cocktail glass.
Garnish with an orange twist.
