Put loose green tea in a teapot. Add 1 cup of hot water to the teapot. Wait for 1-2 minutes. Dump that water out. Do not use it. Fill the teapot with 4 cups of clean water. Put it on the stove top until it starts boiling. Turn off the heat. Add sugar and mint leaves. Serve it by pouring the tea as shown in the picture. Then transfer the tea between 2 glasses several times so it will cool enough to be consumed.
