Our tree is loaded with coconuts:
Two coconuts were on the ground so I picked them up. This is one of them:
I had no idea what to do with them, so I turned to trusty YouTube and found this video made in Costa Rica: How To Pick the Best Ripe Coconut. I decided to practice opening the second green coconut following these instructions. Using our machete very, very carefully I began by hacking off the indicated end. Machetes are really scary to use, to my mind, so I stopped and got a kitchen knife which worked pretty well and was less dangerous. Until I got to the hard inner nut, the green outer shell was easy to cut through and eventually a hole opened up and I could see coconut water. I think I hacked off more than I needed to.
Dropped in a straw and, voila, a refreshing drink!
