The weirdest shell you should try in Phu Quoc is “Nhum”. It is brown and at appearance looks like a coconut after its green skin has been taken off. There are two ways to eat “Nhum”: raw or well-cooked. If your stomach is experienced with handling raw food, you should not miss trying raw Nhum.
When you order a “Nhum”, the seller cut the whole It into half just like cutting the coconut horizontally. Then, you squeeze lime juice into Nhum, use a spoon to scoop out the meat from the shell, dip it into wasabi sauce and savor. The fresh taste and the sweet flavor combined with wasabi sauce and the sour of lime is too good to deny a second help.
