Progressive Orangutan

For the listed 1 dash orange bitters, use the source blend of equal parts Fee orange bitters and Regans orange bitters.

Chill a martini glass in advance to ensure optimal temperature for serving.

Stir the rye, dry vermouth, Bigallet China-China, and orange bitters with ice in a mixing glass until well-chilled.

Strain the mixture into the prepared martini glass.

Express the oils from an orange peel over the cocktail, allowing its aromatic essence to enhance the drink.

Finally, gently place the expressed orange peel into the glass as a garnish.
