2 oz. Dry gin
1 oz. Vodka
½ oz. Cocchi Americano aperitif
Place all ingredients in a shaker with crushed ice. You can stir them, but we've found that shaking works even better (Bond was right). Strain into a martini glass. Twist a slice of lemon peel over the top so the oils spread into the glass and drop the peel in after.
A little note about this cocktail, which was developed in honor of James Bond and was originally his drink of choice. This is one cocktail where the quality of the ingredients you use will shine through in the finished drink; therefore, use the highest quality gin and vodka to make the best Vesper. We like Plymouth or Leopold's gin and Vodka 14. You will frequently see Lillet Blanc recommended as the third ingredient rather than the Cocchi. Lillet will work, but it will make an entirely different cocktail. The reason Lillet is often called for is because Lillet formerly made a version called Kina Lillet. While it was also a light fortified wine like Lillet Blanc, it contained bitter ingredients that made it much more akin to Cocchi Americano. So to produce the most accurate and, in my opinion, best kind of Vesper use Cocchi instead.
