1 oz Pierre Ferrand Dry Curaçao (uncolored)
1 oz Martell VS Cognac
Fill shaker with ice, shake, strain into cocktail glass, twist lemon peel, garnish, serve. — This Straub 1913 Duo with the unusual call for Curaçao Brun (not readily available here) has been modified in my preparation by the use of a Curaçao which necessarily presents a different flavor profile as well as color. In any event, the drink appears to be a local phenomenon in Straub and Grohusko which did not afterward gain traction.
