- 1 cup granulated sugar
- 1 4-inch piece fresh ginger (thinly sliced)
- 1 cup freshly squeezed lemon juice (about 6 lemons)
- 1 cup freshly squeezed lime juice (about 7 limes)
- 1 cup vodka
- 1.5 liters club soda
Combine sugar, ginger, and 1 cup water in a small saucepan. Boil over medium-high heat, stirring occasionally, until sugar dissolves, 2-4 minutes. Cool completely; strain. Stir together ginger syrup, lemon and lime juices, and vodka in a large pitcher. Just before serving, top with club soda and pour over ice.
