Coconut Milk vs. Nut Milks

chicagomama

I recently made a batch of coconut milk and it was so delightful. Naturally sweet and good. it made me wonder if it wasn't the better way to go? Coconut has so many nutrional benefits and the pulp can be used for such great recipes. I am talking about milk made from a mature coconut--I just pulsed the meat with water in a food processer and drained it out in a milk bag. At $199 per coconut, It seems this is the more affordable option as well. So...any reason why this does not seem to be as popular as nut milks?
