In Marshallese it's called "Yu".
It's really delicious.

First step: Sprout lots of coconuts. Take all the brown coconuts in your yard and half-bury them in damp places. Coconuts don't sprout until the fibers of the husk soak up fresh water. A coconut can float in salt water forever without sprouting.
You weren't going to eat those coconuts anyway, so might as well sprout them. It's emotionally hard to kill such a beautiful hopeful thing as a sprouting coconut. Until you find out how delicious it is. You'll want to get a lot of them sprouting so you won't feel like you're removing coconut trees from the world. Also you might want to plant some and let them grow to trees. An old Marshallese man told me the secret of growing good coconut trees was to bury the nuts deep so the roots get a good foundation. I think he said he buried his two feet down.
Step 1: Husk It
I had a pickaxe handy so I used that.
I wanted to leave the sprout in one piece for photos, so I used the chisel end of the pickaxe.
The fibers run lengthwise. Jam the chisel between them.
Jam the nut onto the chisel as shown and pry. Rotate and repeat until it's easy to pull the husk off.
