Because matcha is a powder made from ground tea leaves, it is not steeped in the traditional way. To prepare matcha, add between ½ teaspoon and 1 teaspoon of matcha green tea powder to a cup. Fill a kettle with water and heat to just short of boiling. Pour 6 ounces of the steaming water into the cup of matcha powder.
