Pour water into food processor or blender, add rest and blend.
This makes a simple nut milk that when used instead of packaged soy etc. milk will help reduce all that waste.
Also, i've heard the often the vitamin D2 that they sometimes add is from animal sources, mostly lanolin (from sheep wool), not something i want in my vegan milk.
This milk is best for coffee, mate, and tea, not so good for cereal because it's on the thin side.
Enjoy!
