Chill your martini glasses at least 5 minutes before mixing your cocktail. Fill your cocktail shaker with ice. Add 2 ounces vodka, 1/2 ounce gin and 1/2 ounce olive juice. Shake vigorously over your shoulder until a solid condensation forms over the container. This should be a brisk and focused effort so the drink does not dilute.
Strain into a chilled martini glass and garnish with 3 martini olives threaded onto a toothpick.
