Chill a martini glass. A quick way is to fill with ice and top with water for a minute, then empty.

Place a splash of dry vermouth into the martini glass. Swirl it around to coat the sides, then pour out any that remains.

Add the cocktail onion to the glass. Use a martini pick to allow it to be removed and eaten.

In a shaker full of ice, add 5 ounces of high quality vodka.

Shake the vodka and ice for at least a minute. This allows the ice to break down and gives a nice foam of ice crystals.

Strain the vodka into the glass lined with vermouth.

Serve to James Bond or any other distinguished guest. Enjoy responsibly.
