2 cups ginger
2 cups sugar
4 cups water
1 quart club soda
1 lime

First, you’ll need to make a ginger syrup. Combine the ginger, 2 cups of the sugar, and the water in a medium saucepan and bring to a boil over high heat. Reduce the heat and simmer until syrupy or reduced by half, for 40 to 50 minutes. The syrup will thicken as it cools so don’t over-reduce it. Strain the syrup and reserve the ginger. To make ginger ale, fill four 8-ounce glasses with club soda. Pour 2 tablespoons of the ginger syrup down the side of each glass. Garnish with a lime wedge on the rim of each glass.
