A dry martini is a cocktail made with gin and vermouth, and garnished with an olive or a lemon twist. The term "dry" refers to the amount of vermouth in the martini. The less vermouth used, the drier the martini becomes. Ordering a martini "extra dry" will result in even less or no vermouth added. The classic dry martini recipe involves London dry gin and dry vermouth combined at a ratio of 2:1, stirred with ice, and strained into a chilled cocktail glass. Over time, the amount of vermouth in a dry martini has decreased, with some variations having little to no vermouth at all. The dry martini is a popular and iconic cocktail, and its preparation can vary based on individual preferences and interpretations).
