Make the ginger syrup

• Roughly chop the ginger and add it to a saucepan with the brown sugar and water.
• Bring the mixture to a boil and let it simmer until the liquid turns golden brown.

Fill the glasses

• Add ice cubes to a cup and pour in a couple of tablespoons of the ginger syrup.

Top with sparkling water

• Top the cup off with carbonated water and stir until it looks like a real ginger ale.
