The Boulevardier Cocktail is one of those classic cocktails that everyone should drink on a regular basis. A combination of rye whiskey, Campari, and sweet vermouth the Boulevardier is what you'd get if a Negroni and a Manhattan had a baby cocktail.
Pour the rye whiskey, Campari, and sweet vermouth into a glass filled with ice.
Give everything a really good stir, at least 30 seconds, and strain it into a chilled cocktail glass.
Serve with an orange twist.
Notes
The Boulevardier Cocktail is best served in a chilled glass, the chilled glass and long stir help bring out the flavors and keep the drink cold long enough that you can enjoy it at your leisure.
