Fin de Siècle (End of Century) Cocktail

Begin by selecting a cocktail coupe and pre-chilling it to enhance the drinking experience.

Prepare an orange zest twist, which will serve as the aromatic garnish for your cocktail.

In a mixing glass, combine the Hayman's London Dry Gin, Strucchi Rosso Vermouth, Amer Picon, and a dash of Orange Bitters by Angostura.

Add ice to the mixing glass and stir the mixture until well-chilled and properly diluted.

Fine strain the mixture into the pre-chilled cocktail coupe.

Express the orange zest over the cocktail to release its oils, then use it as a garnish, placing it elegantly on the rim of the glass.
