In a saucepan, combine sugar, water, and ginger. Bring to a boil over medium heat, stirring occasionally until the sugar dissolves. Remove from heat and let the mixture cool to room temperature.

Stir in lemon juice.

Pour the mixture through a sieve and store in a clean jar with a tight lid. Store in the fridge for up to two weeks.

To serve, mix syrup (depends on how tart/strong you like your lemonade) with ice cubes and top with sparkling water. Enjoy!
