The Silver Lining is a Joseph Schwartz original (he’s the founder of NYC’s fabulous Little Branch). A clever riff on the classic egg fizz template, with Licor 43 (or Tuaca, or another vanilla liqueur) providing a balanced sweetness and a compelling flavor.
Like all egg white (or aquafaba) drinks, you should double-strain it through both your shaker’s strainer and a fine mesh strainer.
