In this video, you’ll see how to mix up a vesper, the cocktail that James Bond invents in “Casino Royale.” Though often partial to vodka martinis, Bond’s vesper cocktail is made with both vodka and gin, plus a splash of Lillet blanc. Now then, to shake or to stir? These days, Bond doesn’t seem too troubled either way. Here, the bartender shakes it over ice. You can do as you like. Watch the video, then get the recipe for the Vesper Cocktail. This one packs a Bond-caliber punch.
