I made the cocktail and added two dashes of Angostura Cocoa bitters before shaking and I find it really brought it together nicely. :) I have one question though: I have coupes that are the proper size described in the recipe but my finished cocktail barely made it halfway up :( . Did anyone experience this as well?
Finding the perfect capacity glass for each cocktail is a task, and most modern coupes are a little on the large side. The ingredients total 105ml plus 36% dilution from shaking with ice = 143ml. A 7-oz coupe glass has a capacity of 200ml to the rim, so it would be 70% (roughly 2/3rds) full. If you are not achieving roughly this capacity, then perhaps your ice needs to be left to temper, and/or a more vigorous shake is required.
