The general bartending "rule" is to stir liquor-only cocktails to avoid too much dilution. But in the case of this cocktail, shaking may actually be a good thing because it ensures extra dilution in this stiff drink.
You need 90 ml gin, 30ml vodka, 15ml Tikka Bianco and fresh lemon peel.
In a cocktail shaker, combine gin, vodka, and Tikka Bianco. Shake very well and strain into a chilled cocktail glass. Garnish with a large piece of lemon peel. Serve and enjoy.
Every James Bond fan knows this recipe as the first martini that Bond ordered in Ian Fleming's 1953 book, Casino Royale (or the 2006 movie). Named after the seductive double agent Vesper Lynd, it is possibly the most famous drink order in history.
