In 1927, a young American writer named Erskinne Gwynne moved to Paris to start a literary magazine. He called it The Boulevardier. He gave the same name to the cocktail he created (and frequently drank) at Harry’s New York Bar. This signature drink was equal parts whiskey, Campari, and sweet vermouth.
2 oz Coalition whiskey
1 oz sweet vermouth
1 oz Campari
Place all ingredients in a mixing glass. Add ice and stir for 30 seconds. Allow to sit for 30 seconds, and then strain into a chilled cocktail glass. Garnish with orange peel.
