Boil at least a liter of water. Rinse a small tea pot with about 1/4
cup of the hot water.
Add the tea bag and another 1/4 cup boiling water. Swirl the pot to
wash and rinse the te bag, and pour out the water.
Add the mint leaves and the sugar, and fill the pot with 1/2 liter
(about 2 cups) boiling water. Leave the tea to steep for five minutes or
longer, or set the tea pot over medium-low heat and bring the tea to a simmer.
Remove from the heat, and allow to steep several minutes more.
Gently stir the tea, pour into small tea glasses and serve.
