How to drain, open and deflesh a coconut.

I learnt how to process a mature coconut via my dad. Use a corkscrew to drill out two of the 'eyes'. Flip over and sit over a glass to drain the water.  Use a wood saw to carefully cut in half. You can create a perimeter or just cut right through. Rinse sawdust off with water. Use a butter/table knife to remove flesh. Start from the cut edge, score the flesh then push the blade flat against the shell and twist. It will pop right off with the edible brown skin. If you don't want that you can shave it off with a knife or peeler.
