Mix 3 measures of Tanqueray gin with 1 measure of Stolichnaya vodka and one-half measure of Kina Lillet. Shake over ice until ice cold, then strain into deep champagne goblet or martini glass and add a large thin slice of lemon peel.
Enjoy an amazing drink, one of the best martini variations!
Note: Extratasty has listed the Kina Lillet as white wine in the ingredients list. Nowadays, you probably won't be able to find Kina Lillet. Instead, you can use Lillet Blanc and then add a pinch of quinine powder to the drink in order to emulate the bitterness of Kina Lillet.
