I have a particular fondness for the gimlet, that simple but elegant concoction of gin, fresh lime juice and sweetened lime cordial. For many, the drink conjures images of dames and detectives from noir films, but mine is a more nostalgic affection. The gimlet was my cocktail of choice during my early 20s, when I lived in San Francisco and frequented louche watering holes that played rockabilly and swing tunes. What I have always loved about the drink is its poise — if the martini is the king of cocktails, then the gimlet is the queen.
