Bring 1 1/2 cups of water to a very light boil. Break the cinnamon stick into smaller pieces and add it to the water immediately followed by the cardamom seeds and a tiny pinch of ginger. too much will overpower the other spices.
Simmer for a 5-10 minutes or until the water turns slightly yellow and emits a pleasant smell. The cardamom seeds will swell slightly.
Turn the heat off, add the tea leaves, and stir.
Let steep for 1-3 minutes or to taste.
Strain and enjoy!
