I recently purchased a bottle of Guillaumette Genepi and was trying to figure out how to use it. Since a "proper" knight cocktail calls for yellow chartreuse, I figured I'd give it a try and name it after one of the New Orleans west bank's more classy establishments.
1.5 oz Tiffon VSOP Cognac
.5 oz fresh lemon juice
.25 oz Genepi
.25 oz Cointreau
Shake like you're working behind the bar in the dark and smokey Naughty Knight Lounge at 2 in the afternoon. Strain into a cocktail glass (chilled if you're klassy). Enjoy.
