I have been attempting to make ice blended coffee at home. I use
coffee, chocolate coco powder, milk, and crushed ice; all spun in the
blender...naturally.

The taste is not so bad, however, the drink seems to separate almost
immediately; the ice bits float to top and separate from the
liquid at bottom.

Question: Does there exist an ingredient I can add that will keep the
drink homogeneous?...and not harm the taste?

Thanks,

Tom
