Bring water in a kettle or pot to a boil, observing the bubbles and steam release with a gentle whistle or simmering sound.
Pour the hot water over the green tea bag placed in a teapot or cup, and steep for 2-3 minutes until the water turns a vibrant greenish-golden hue and the aroma begins to develop.
Remove the tea bag using tongs or a spoon once the desired strength is achieved, watching the bag lift out showing a damp, darkened exterior.
Add a pinch of ground cinnamon directly into the hot tea. Stir gently with a spoon to distribute the spice evenly, noting the swirl of cinnamon creating a subtle spiral as it dissolves.
Observe the final appearance: the tea is clear with a golden-green color and a fragrant aroma of spice and tea, ready to be enjoyed.
