Whether, like James Bond, you prefer your martini shaken, not stirred, or not, today is Martini Day, so you now have the perfect excuse to enjoy one. World Martini Day is celebrated on the third Saturday in June, and marks the end of Gin Week, which starts with World Gin Day on the second Saturday of June. Our recommended recipe is a synthesis of two executions: the Gibson, with two cocktail onions, and the classic Dry Martini, with gin and olives.
