Method
Dry shake (if using egg white):
- Add bourbon, lemon juice, simple syrup, and egg white to a cocktail shaker (no ice). Shake hard for 15 seconds to emulsify the egg white.
Wet shake:
- Open the shaker, fill with ice, close, shake again hard for 15 seconds until properly cold.
Strain and garnish:
- Strain into a chilled rocks glass over fresh ice (on the rocks) or into a coupe (up).
- If you used egg white, drop two dashes of Angostura bitters onto the foam and drag a toothpick through to make a pattern.
- Garnish with a maraschino cherry and an orange slice.

Notes
Egg white is optional but recommended. It softens the drink and creates the classic foam top. If you do not want raw egg, use 3/4 oz of aquafaba (chickpea liquid) for the same effect, vegan and pasteurised.
Boston Sour: standard whiskey sour with red wine floated on top. Different drink, also good.
Don't skip the dry shake if you are using egg white. Skip it and the foam never forms properly.
