1. Get your orange zest off an orange before you peel it. The easiest way to get fresh orange zest is to simply use a clean orange peeler to shave a bit of orange peel off. Collect 1 tbsp's worth.
2. Peel your oranges well using a knife. Cut off most of the white rind so that you just have nice, glistening oranges with very little white rind left.
3. Add all ingredients to your high-speed blender.
4. Blend well.
5. Enjoy your raw orange smoothie!
