My cousin Erin is chopping a coconut with a bush knife. We took turns with our parents cutting it open.
Coconuts have a one-inch thick husk outside, then a hard shell covering, then a lining of coconut meat, then coconut milk inside. The shell inside is hard as a rock.
The milk is dried up in old coconuts. You need to shake it first to hear the milk swish around.
I really like the coconut meat.
