With the calvados, this is a great cocktail for the fall. And the name makes me think it might be good for Halloween. It might be a little heady to serve before Thanksgiving dinner, but maybe not.
Chill a martini glass in the freezer. Add ice to a cocktail pitcher. Pour in calvados, Chartreuse, and Benedictine. Shake in bitters, then stir. Strain into martini glass and garnish with a cherry.
