Add Grey Goose, blueberry jam, basil, cranberry juice and bitters to shaker. Add cubed ice, shake until chilled. Serve into a martini or whisky glass.
Tip: Although not always taken note of, the quality of the ice you use plays a huge factor in your cocktails. It is also believed that the more ice you add the more it will dilute, but in truth it is the opposite. The colder the drink is, the less it will dilute.
