Stir the vermouth and Campari together in a 2oz sherry glass. Gently layer the unbroken egg yolk on top, then carefully layer the gin atop the yolk. Beat the egg white until stiff with a whisk or in a cobbler shaker with a spring. Then cover the gin layer with the egg white. Garnish with a drop or 2 of the bitters. #roomtemperature #layered
From Frederic Yarm, Cocktail Virgin Slut Blog. It is recommend you drink the drink by: 1) drawing the froth first with a deep breath, pause. 2) take 1/3 of the remaining liquid without disturbing the yolk, pause. 3) shoot the remainder, breaking the yolk in your mouth.
