Tried this out before I got coconut milk.
The coconut water wasn't strong enough for the rum.
Blended, it's frothy, tropical fruity, and quite delicious. It was way better tasting the second time I made it. I was a bit heavy-handed with the rum on the first try due to what I cool the "after work pour". Cheers! Next time I try with cream of coconut if I can find it. :P
