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.
Step 2: Admire the Sprout
Step 3: Whack It and Crack It
That means tap it around the equator with a rock, light hammer, or the back of a machete.
Don't hit it too hard. You don't want to break through and mash the food. When a crack starts it will grow toward the place you're tapping.
When it breaks in half you can use the same process to break the shell into smaller pieces.
The stem stayed with the other half of the nut.
Step 4: All Parts Are Edible
There's nothing bad about a coconut tree or any part of it.
You can eat any part that appeals to you.
Step 5: Eat and Enjoy!
It's probably really good for you.
The remaining coconut meat around the edge isn't my favorite part.
Time to get some chickens or maybe a baby wild pig to share it with.
Step 6: Just Barely Sprouted
It was just starting to sprout. That little nubbin formed inside with the stem coming out of it. It starts to absorb the meat around the stem. The coconut at this point is mostly full of water, which I drank. The meat of a coconut at this stage tastes much better to me than a regular coconut.
