I specifically created this drink to be the "house cocktail" for my home bar, which I’ve nicknamed the "Black Feather". In my original recipe I used my own home-made bitters, but lacking that Angostura, or Fee's Old Fashioned Bitters will work just fine.
Garnish: Lemon twist
Stir with ice. Strain into a cocktail glass.
