3 ounces gin
1 ounce premium vodka
½ ounce Lillet Blanc
- Holding a large cube of ice in the palm of your hand, use the back of a stirring spoon to crack it into large pieces; place in a mixing glass. Repeat with enough ice to fill glass. Add gin, vodka, and Lillet Blanc and, using a bar spoon, rapidly stir 50 times in a circular motion (the outside of the shaker will become very cold and frosty).
Strain martini through a strainer (or a large slotted spoon) into a chilled flute or coupe glass
Using a small knife, remove a 1" piece of peel from lemon; it should be stiff enough to provide some resistance (a little white pith is okay). Twist peel over drink to express oils, then rub around rim of glass. Float peel, yellow side up, in martini.
