Skewered crystallized ginger adorn glasses of The Big O--a vodka cocktail with agave nectar, lime juice, and ginger beer.Use agave nectar instead of simple syrup for a healthier beverage; it has a much lower glycemic index than sugar.
Divide vodka between 2 glasses filled with ice. To each glass, add 1 teaspoon simple syrup or agave nectar and about 1/2 tablespoon lime juice; top each with about 1/3 cup ginger beer. Stir to combine. Garnish cocktails with skewered crystallized ginger.
