Every-Body's Irish Cocktail

Chill a cocktail coupe in advance to ensure optimal serving temperature.

Prepare a garnish by selecting a green maraschino cherry.

Combine the Irish whiskey, Green Chartreuse or an alternative herbal liqueur, Giffard Peppermint Pastille crème de menthe, and chilled water or mineral water (if not using wet ice) in a cocktail shaker.

Add ice cubes to the shaker and shake the mixture vigorously until well-chilled.

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

Garnish with the prepared green maraschino cherry.
