Many thanks for all the replies. I'll try looking for the canned ones, but I just can't imagine it being the same as that of fresh coconut. I'll check it out though.
Collettes !!!! My usual travels to the south (when I was still in Manila) would not be complete without buying loads of Collettes! Grabe, sobrang miss ko na pala ang pinas!
I am toying with the idea of coming back to the Philippines actually to recuperate. Then I could have all the buko I need. But the timing is not favourable, so I'll just try and sort myself out while in here.
Salamat sa lahat!
