A Rocky Green Dragon combines gin, green Chartreuse and Cognac. I got my recipe from The New York Bartender's Guide. You'd think there'd be a great story behind such a colorful cocktail name but I couldn't find anything.
My wife found the gin to be a bit much - I used Prairie Organic for this one. A lighter choice might have worked better. Also, as much as we both enjoy Chartreuse, she felt this cocktail suffered from the lack of a citrus "top note" like lemon or lime juice.
This is why we experiment.
