Last night I was given a seat at the bar for dinner, and in an idle moment I asked the bartender if he knew how to make a martini, since he was obviously mixing away at a lot of other drinks. It turns out he didn't. No one here seems to know how to make this, the most basic of mixed drinks. I make an excellent martini and offered to teach him.
First you must have Martini and Rossi dry vermouth. He had this. Only dry vermouth is used in martinis. Then gin, mixing them at about 3 or 4 parts gin to one of vermouth. Shake over ice. According to Nick Charles in The Thin Man, a martini should be shaken in waltz time.
He asked me if I wanted a job.
