When I was a kid, we would tap a nail through the hull to drain out the liquid and then smash it with a hammer. You have to tap a couple of holes so it will drain properly, otherwise it can't get air inside. The fresh coconut water was the best part of the whole thing. I haven't bought a whole one at the grocery store here in years, but I was reminded of how good they are when I was in India.
“If I didn't define myself for myself, I would be crunched into other people's fantasies for me and eaten alive.” --Audre Lorde
