I put about 10 icecubes in my blender, put the shake mix on top then the water ( the normal 8oz) and wizz it up. It makes just over a pint of cold, frothy shake that is yum. Its the only way I can drink them now!!!
I actually use less water. I fill my glass to the recommended amount, drink quarter of it and pour the rest into my blender. I then add about 10 ice cubes and whizz. It does need a good knock every now and again because it goes so thick. But it is so yum! And very filling.

I use 400-500 mls water with 4 ice cubes plus the shake in the blender... gives a lovely creamy shake, also adds to my water intake over the course of a day.
