Another excellent drink. The descriptor of this as "spirit-forward and just on the rich side" is very apt. As I generally have a glass of port as my after dinner drink I, as is my custom, I drank this as my pre-dinner cocktail tonight and very much enjoyed it. While indeed rich, it worked well for me. My only suggestion for consideration as a fan of Absinthe, is that I increased the Absinthe which for me worked nicely.
Another excellent drink. I was hesitant about the 3 drops of saline but it works well given the bitter element from the Campari. Difford's suggestion for the "original" Fogerty cocktail (using De Kuyper 'Dutch Cacao' Creme de Cacao instead of Crème de cassis) of serving on-the-rocks if one finds it too spiritous / bitter even with the saline, would work equally well here.
Excellent with terrific balance of sweet and sour. The mix of gin and brandy (I used Armagnac de Montal VSOP) blended nicely without either overly predominating. My only comment would be that as much as I am a fan of saline, I only used one drop. I would say that for me that was a good decision as there wasn't really an abundance of sour or bitterness that needed taming and I believe one drop is all that wasI needed to act as a general flavour enhancer.
As per other comments, a really excellent cocktail. I'm thinking next time, notwithstanding this is one of those equal parts cocktails, I would like to try increasing the Mezcal a tad just to give it a little more oomph. Not sure if that will throw off the balance too much; we will see!
