Clint Eastwood (Mike Ryan) with Michter's rye whiskey, green Chartreuse, Angostura bitters, demerara syrup (I used half demerara syrup half gum syrup).
The generous dose of bitters (1 bar spoon, as much as the Chartreuse) was fun and actually less in-your-face than I would have imagined. Very good Old Fashioned variation, and I am falling more and more in love with the Michter's rye.
