Agree with Chris that vermouth dominates (I also used Carpano Antica) and think I would have preferred a little more gin. For the "dash" I used 1 ml Absinthe and would consider using of that next time as well. Intrigued by pomegranate molasses and might try that next time as well.
Pleasant and herbal/complex without being too sweet. The vermouth dominates so use something good; I used Carpano Antica. Reducing Craddock's proportion of gin to half that of cognac leaves the gin flavors present but not dominant. Decided to use pomegranate molasses rather than grenadine, which gave the drink more weight. The tiny trace of absinthe (I tried measuring "1 dash" since my bottle doesn't have a shaker top) was not detectable. Can't believe I'm the first to comment on this drink!
