2 oz of Vodka
1 dash of bitters
3 oz of club soda (or clear soda)
1 1/2 oz of Lime Juice
1 tsp of superfine sugar (or sugar)
Add the lime juice, sugar, vodka and bitters to a cocktail shaker half-filled with ice cubes, and shake well. Almost fill a collins glass with crushed ice and stir until the glass is frosted. Strain the mixture from the shaker into the glass, and add club soda. Serve with a swizzle stick.
