Chill a martini glass in advance to ensure the perfect serve.

Prepare an orange zest twist to use as a garnish.

Stir Dubonnet, Amer Picon, and Cointreau L'Unique triple sec liqueur with ice until well chilled.

Fine strain the mixture into the pre-chilled martini glass.

Express the orange zest twist over the cocktail to release its aromatic oils, then place it in the glass as a garnish.
