In a small saucepan, add sliced ginger and water. Bring to a boil, cover and simmer for 10 minutes.
2 inches (30 g) freshly, sliced ginger root, 1 cup water
Meanwhile, combine cane sugar and matcha in a liquid measuring cup that will be large enough to stir in the ginger infused water later.
1 cup cane sugar , 1 tbsp matcha green tea powder
After 10 minutes of simmering the fresh ginger and water, use a slotted spoon to remove the sliced ginger from the ginger-infused water. Strain through a fine, mesh sieve if desired.
Carefully pour the ginger-infused water over the matcha sugar and immediately begin stirring. Stir until the sugar is completely dissolved in the hot water. Allow this to cool to room temperature.
To serve, add 1-2 oz. of the matcha-ginger syrup to a drinking glass (start with less and add more if desired). Fill glass with ice followed by 2-3 oz. of fresh lemon juice. Top each serving with sparkling water and garnish with a lemon slice.
1 cup freshly squeezed lemon juice (about 5 large lemons), favorite sparkling water, sliced lemon for garnish (optional)
