Bijou

This classic 19th-century cocktail’s name means “jewel” in French, in supposed reference to its combination of gem-colored spirits: diamond-clear gin, ruby-red sweet vermouth and emerald-green Chartreuse. While the original — often attributed to Harry Johnson, who published a recipe in the 1900 edition of his “New and Improved Bartender’s Manual” — called for equal parts, this variation skews the drink toward modern palates by reducing the amount of green Chartreuse. The final drink is balanced and dry, yet still plenty herbal. Serve and sip as is, or split between two very small, very pretty glasses for a petite-in-stature, big-in-flavor nightcap.
