You will need white sugar, 1 strip of lemon zest, 1.5 oz of vodka, 1/2 oz lime juice, 1 oz sweet and sour mix, and1 c crushed ice. Moisten the edges of the martini glass with a small amount of lime juice, and then dip the moistened glass in the sugar. Place the lemon zest in the glass. In a shaker combine the vodka, lime juice, sweet and sour mix, and ice. Shake and strain into the martini glass. Cheers!
