Bring a kettle of water to a boil. Add boiling water to a teapot that holds about 4 cups water, and swirl to warm. Discard the water and add the tea, 24 mint leaves, and sugar to the teapot. Pour the quart of boiling water into the teapot and swirl once or twice to dissolve the sugar. Allow the tea to steep for 5 minutes.
Pour the tea through a strainer into small decorative Moroccan glasses or teacups. Garnish each with several fresh mint leaves.
