Pour in ½ cup of the boiling water, swirl to rinse, then discard the water.
Add the remaining water and steep for about 5 minutes.
Add sugar or honey if desired and serve.
Notes
Substitute for tea bags: 1 tablespoon of loose-leaf gunpowder tea is roughly 3 to 4 green tea bags, for a stronger tea adjust the steeping time for 2-3 more minutes.
