I recently took the leap and purchased a bottle of Green Chartreuse for the home bar. So after trying a Last Word and Final Ward, I found this, a variation on a Sazerac from Spice Kitchen and Bar in Cleveland. It gets a boost from the complex, herbal flavor of Chartreuse and a bright dash of lemon bitters. My favorite use of GC so far.
2 1/2 oz. rye whiskey
1/4 oz. green Chartreuse
1/2 tsp. simple syrup
2 dashes lemon bitters (I also liked Fee Brothers Whiskey Barrel Bitters)
Stir rye, Chartreuse, and syrup over ice in a cocktail mixing glass. Add a splash of absinthe into a coupe glass, and swirl to coat the inside of the glass before discarding the absinthe. Strain rye mixture into glass; top with bitters and garnish with a lemon twist.
