Ingredients
- 1/2 cup thinly sliced peeled ginger
- 4 plump stalks of fresh lemongrass, cut into 2-inch lengths and smashed, plus stalks for garnish
- 6 cup water
- 1 cup sugar
- 3 tbsp freshly squeezed lemon juice
- lemon wheels, for serving
- ice cubes, for serving
Directions
In a medium saucepan, combine the sliced ginger with the smashed lemongrass and 4 cups of the water and bring to a boil over high heat. Stir in the sugar. Cover and let the ginger-lemongrass syrup steep off the heat until cool, about 2 hours.
Strain the syrup through a fine-mesh sieve. Discard the ginger and lemongrass. Stir in the lemon juice and the remaining 2 cups of water. Refrigerate until chilled.
Make the soda according to the manufacturers' directions. Serve in tall glasses over ice, garnished with lemon wheels and lemongrass stalks.
