Grind the coconut in your blender or spice grinder until fairly finely ground.

Add 1 cup of water to the ground coconut in a high powered blender (like Blendtec) and blend on high for 1 minute.

Add enough water to make 5 cups of coconut milk.

Blend on high for 3 minutes.

Enjoy and store in the refrigerator.

If using this to make coconut milk kefir : and you want a thinner consistency, strain this mixture through a nut bag to remove the small pieces. For a thicker consistency, leave the pulp in. It might stick to the kefir grains but it doesn't hurt them.
