A room temperature cocktail created for a Women of the Wild West night at the Blue Room in Cambridge circa 2013. A curious drink named after a curious woman... for a curious bartender whose birthday was that night; he loves rhum agricole and he requested a Scaffa for the night.
1 1/2 oz Aged Rhum Agricole (will work with Aged Cachaça too)
1 oz Drambuie
1/2 oz Cynar
1 dash Angostura Bitters
Build in a rocks glass -- no ice. Give a quick stir to mix, and garnish with a grapefruit twist.
