Place 4 cups of water into a pot. Put on high heat. Once you see small bubble start to form on the bottom of the pot, turn off the heat (no need to bring the pot up to a roaring boil). Then place in 4 teabags. Steep for 2 minutes.
Let it cool down. Then place in refrigerator and chill.
Place a good amount of ice cubes into a cup. Fill the cup half-way with mango juice. Then fill the rest with the cold Ceylon Tea. Stir and enjoy!
