Bring the water to a boil. When it's boiling, add the sugar and stir until dissolved. Turn off the heat.
When you're ready to serve, pour into small glasses, using a tea strainer. If you can, try pouring a good few inches from the glass - this cools down the tea, and creates a light foam on top that is traditional. You can also chill this tea and serve over ice on hot days. Refreshing, and great for your digestion!
