POUR Fernet Branca into ice-filled glass. Separately MUDDLE raisins in base of shaker, add other ingredients and SHAKE with ice. Finally DISCARD contents of glass and strain contents of shaker into the Fernet Branca coated glass.
Not that far removed from a Sazerac cocktail, this is innovative and great tasting.
