Place all the ingredients, except the orange into a high speed blender (I use an Optimum 9200A).
Grate the zest of the orange and add to the rest of the ingredients. Peel the orange and add the flesh and ¼ of the peel.
OR you could just cut the whole orange into quarters and add the entire fruit.
Blitz for 30 seconds or until you have a smooth drink.
Notes
Makes two very large glasses, four medium glasses or eight small glasses.If you don't have a high powered blender, just squeeze the juice from the orange before adding and omit the rind.Please note: calories and other nutritional information are per serving.
