Prepare a tall glass full of ice then add the Lime vodka, next add the Lime juice. Add 1 part Ginger Simple Syrup (1 part sliced fresh ginger, 1 part sugar, 1 1/2 part water, boil until syrupy) Shake on with ice, serve on ice with crystalized ginger...this is so yummy. Don't skimp...use fresh limes, the best quality of lime vodka (Hanger One Kaffir Lime Vodka) and most important make the ginger syrup....If you don't have fresh ginger, use organic drid giner (I use Rishi Organic Ginger Tea)Ginger syrup will keep in fridge for a couple of weeks.
