Start by cracking the coconut then remove the shell. When removing the shell insert the knife between the coconut and the shell. Wag the knife along and the coconut should separate easily. Note also, do not use a sharp knife if this your first time doing this.
Grate the coconut. Note: To keep the process traditional we used a grater, but the blender would do a fast job of this.
Add 3 cups of water to the grated coconut and pick up handfuls of the coconut meal and squeeze. Place the squeezed coconut into another bowl.
Do this process 4 times ( = 12 cups). Use immediately or freeze for later use.
