Have you see this fruit before? I am sure a lot never or maybe you did come across it at native market but you never care to pay a look at it before.
It is actually a fruit that can only be found in Sarawak area. Usually local called it Buah Engkalak (Iban language) while the Melanau called it Buah Tebuluh. It's the fruits from a wild plant.
How to eat? Good question! No cooking is needed here. It's very simple.
First of all, take off the stalk on top of the fruits. You just need a gentle pull to remove it. Then, of course wash it with plain water to clean up the fruits.
First, soak them in the warm and salty water until the fruits are soft enough to consume. The fruits itself are soft actually, but without some simple process like soak them in water, they are still not suitable to eat. However, I heard if the fruits are soaked in the water, their taste will be washed away as well. Therefore, it is not as tasty if you process them in this way.
I more recommend the second method. Just take a spoon, smash around the fruits gently with it. This is to make the fruits softer and looser so that they are good to eat. Then, apply some salt on the fruits. Leave the fruits aside for about 15-20 minutes or more. Then, they are ready to be eaten.
There is a perfect match when eating buah Engkalak - the "Sago seeds"! It's not the real seeds from Sago plant but is a snack type of food made by Sago flour. You can get it in native market as well.
