Sideburn Sour

Rinse a Martini glass with absinthe and set it aside.

In a mixing glass, combine the bourbon, red wine, orange juice, simple syrup, and egg white.

Dry shake the mixture vigorously with a cocktail coil to emulsify the egg white.

Add ice to the mixing glass and shake again until well-chilled.

Strain the cocktail into the prepared Martini glass.

Dot the finished cocktail with a couple of drops of bitters and elegantly run a straw through the bitters for a marbled effect.
