Blend the ingredients in the order listed.
Blend the ingredients a few at a time so that your blender can cope with the work, unless you’ve got a high powered blender, then you might be able to add them all in at once.
If it gets too thick, add more water as necessary.
If your blender has made the smoothie too warm, you can either cool it down in the fridge or freezer, or add some ice cubes to it which may make the recipe thinner.
You could also use frozen fruit which keeps it cool while blending but may make the recipe thicker.
