I have been "lurking" now for quite some time. Finally, I feel I have something to add. Having lived in Thailand for 2 years, Mary, I believe the coconut "huts" as you call them, are young coconuts, the husks trimmed to look like a hut. It should have a top (roof) that can be removed. The inside is simply eaten with a spoon. It tastes very good on a hot day in Bangkok. As for how long it can be stored, I am not sure. They are usually eaten quickly. I would assume if it is still white, smells good, it can be eaten. Donna
