Some fresh buko stalls/stores out there are selling coconut juice and meat that aren't the freshest possible. Some have bottled the juice and chilled them to last a few days. Then they add a few strips of meat that was already prepared in advance. Buy coconut in its original form and you're sure its fresh! Its the cheapest this way, and you're assured of the best nutrients and cleanest product from the best source - nature!
A few years ago, I posted about coconuts here. The coconuts used to be P25. each (in the city), now its P35. each. But its still much cheaper than buying it in commercial stalls or ordering it from restaurants.
I buy coconut at a neighborhood street vendor, he already knows that I want the young coconut, with the outer shell chopped, but with the meat and juice still intact. I take it home and chop it open myself, to make sure its perfectly clean.
Each coconut is good for two servings.
