With Tanqueray 10 really outstanding. It may remove Monte Cassino from my No.1 cocktail position. Chartreuse shines more in this version. There is also another variation with calvados which is very delicious: Widows Word.
Yes, this is an excellent, well balanced drink. Perhaps slightly on the sweeter side with the Benedictine, but it works well. Definitely in the rotation.
I don’t have Yellow Chartreuse, but I used Genepy L'Ancienne instead and added a barspoon of Elixir Végétal to enhance the complexity—it worked perfectly!
