As I already have posted in rec.food.veg:

The simple secret is that you should use a shaker, the same thing barkeepers
use
to mix cocktails. We use to drink a soy powder that you mix with water or
milk instead of breakfast if we are in a hurry. Therefore we use two of
these tupperware mixers and drink the mixture afterwards immediately and
directly from the cups - no remains at the bottom at all. Just perfect!
