This isnt a martini, and its definitely not a highbrow tipple but its a welcome refresher on a hot day. Sort of like a sports drink for the booze set. Its also one of the few ways we know of to use up pepper vodka, if you have it. We usually dont shake vermouth; it has a tendency to make large, ugly bubbles when agitated. We relax that rule for this drink, since theres so little of it. The oily nature of the brine makes it difficult to mix, so a good hearty shake does this drink good. Not a fan of olives? Try it with pickle juice
