Since Saint Patrick was of Gaelic descent, it seems appropriate to mix a little Chartreuse, courtesy of France’s Carthusian monks, into this cocktail that shares a name with a town in southern Ireland.
2 oz. Irish whiskey
3/4 oz. Carpano Antica Formula or other sweet vermouth
1/2 oz. green Chartreuse
Tools: mixing glass, barspoon, strainer
Glass: cocktail
Garnish: lemon twist
Combine ingredients in an ice-filled mixing glass and stir. Strain into a chilled glass and garnish.
