Mixing-glass half-full fine ice, two dashes Angostura bitters, two dashes orange bitters, one- third jigger French vermouth, one-third jigger Italian vermouth, one-third jigger whiskey. Mix and strain into cocktail-glass.
One-third of a jigger is only 1 Tablespoon. Cocktails at the end of the 19th century were smaller than today's so instead of using 1/3 of a jigger one can use 1 ounce each of sweet vermouth, dry vermouth and whiskey and increase the bitters to 4 dashes each for a contemporary size cocktail (i.e., 3 ounce)
The original recipe does not identify the brand of vermouth or the type of whiskey. Based on the date of publication, rye whiskey was most likely used.
