Gibson

In one story, Gibson challenged Charley Connolly, the bartender of the Players Club in New York City, to improve upon the martini’s recipe, so Connolly simply substituted an onion for the olive and named the drink after the patron.

6cl (6 parts) gin
1cl (1 part) dry vermouth

Stir well in a shaker with ice, then strain into glass. Garnish and serve
