Allow the teabags to steep (set in the water) for 20-30 minutes.
Dispose of teabags and allow liquid to cool.
Pour liquid into ice cube trays (I was able to fill four trays).
Place in the freezer for 6-8 hours or until the liquid is frozen.
Pop the “blue” cubes out of the trays.
Use a blender or food processor to crush the ice cubes
