This is really too easy to call a recipe. Muddle a few chunks of peeled English cucumber and a few mint leaves with some vodka and let it steep for half an hour or so. Chill a cocktail glass. Fine strain two ounces of the vodka into an ice-filled shaker and add 1/4 ounce of dry vermouth. Stir well until the tin gets frosty and strain into glass. Garnish with a cucumber slice and mint sprig.
