Blend all ingredients well until frappy. Pour into a pretty glass, sprinkle cinnamon on top, and enjoy. If you don’t have the powdered yerba, you can brew a teabag in the sun for about 10 minutes, and then use that water and tea as your base!! You can also serve it warm by adding no ice, and blending really well until nice and warm in your blender. That was the way I first tried it, and it was very good. Enjoy!
