Add the tea bags and boiling water to a large measuring cup with a spout. Steep for 5 minutes, then remove the tea bags (press the bags against the side of the cup to release more of the tea!)
Add mixture to a 9 x 5 loaf pan and freeze for at least 6 hours. When ready to serve, boil and strain boba pearls and add to the top of the ice cream. Enjoy!
