1 C. crushed ice
6 T. chilled lemon-flavored vodka
2 T. chilled lemon-flavored liqueur
4 tsp. lemon juice
2 thin strips (3 in. long) lemon peel
Pour sugar onto a small, rimmed plate. Rub rims of two martini glasses with lemon wedge to moisten, then dip rims into sugar to coat. Place ice in a cocktail shaker. Add vodka, liqueur, and lemon juice. Shake until mixture is very cold, about 10 seconds. Strain into glasses. Garnish each with a twist of lemon peel.
