2 oz gin
1/2 oz green Chartreuse
1/2 oz lime juice
Shake with ice and pour into a cocktail glass (or at Green Street, a champagne coupe). Recipe from CocktailDB.com and I assume Green Street does not vary greatly from this recipe.
For my second and last drink last night, I followed up the Avery's Arrack-ari with a lime drink of similar complexity, an old favorite called the Green Ghost. For some reason, Andrea does not care for the combination of gin with either Chartreuse (despite the fact that she loves both ingredients separately), so often I will choose these cocktails when I am out and not mixing for two at home. Andy was more than happy to make it for me, although his super-excitement shows through when Andrea asks for a suggestion on a glass of bourbon like she did last night.
While googling for a drink history of this cocktail, the first entry was by Lauren Clark of DrinkBoston.com, which is interesting in that she walked into Green Street after attending the craft beer fest and sat down next to us to chat as I ordered and drank my Green Ghost. The history of the cocktail is pretty slim save for CocktailDB citing "J. B. Hurrell" as the creator.
