Picking up where we left off, with the Sidecar …
Versatility is the hallmark of a good cocktail. A small change can result in a vastly different experience. The Sidecar serves as a perfect example. Replace the Cointreau with, say, the complex French liqueur chartreuse and you might as well give the drink a new name. Maybe something that connotes Gallic elegance like, say, the Champs-Élysées.
But which chartreuse? That’s the question.
Yellow chartreuse, on the other hand, has a more sedate flavor that would seem a better match for cognac. Flipping through my 1956 edition of Patrick Gavin Duffy’s Official Mixer’s Manual, I wasn’t surprised to see him call out the lighter brand of chartreuse.
There’s room for still more invention. Washington Post cocktail authority Jason Wilson offered a variation forsaking sugar in any form and incorporating sparks of orange that add a higher register to the drink. Contrast his version with the Zig Zag’s for a sense of the subtle range that’s possible within the spectrum of a single cocktail.
