Add the rye whiskey, Punt e Mes, and maraschino liqueur.
Stir vigorously for 30 seconds, then strain into a cocktail glass.
Garnish with the cherry.
Notes
Adapted from a recipe by Enzo Enrico of Milk & Honey, New York If you substitute ½ ounce of yellow Chartreuse for the maraschino liqueur, you will have what is called a Greenpoint. If you substitute ½ ounce of Cynar and ¾ ounce of sweet vermouth for the Punt e Mes and the maraschino liqueur, you’ll have a Little Italy.
