The terung asam or sour eggplant (or terung iban) as most dayak people called it in Sarawak. It is a rare type of eggplant where you never find in other places. It is grown very well in Sarawak of East Malaysia (part of Borneo Island) and are sold commercially at the vegetables market. Sour eggplant is one of the favourite vegetable, in Sarawak among the native ethnic groups, malays or even the chinese people. It has thorny tree and leaves, so you need to be careful when picking the fruits. The fruit is green when it is still young as seen in the picture and when it is riped it turn a bright yellow or slightly orange. The ripe fruits are sour. It has alot of seeds. 
This is the terung asam (sour eggplant) I grew last year and has flowers too but it didn't bear fruit except one. It barely survived. I guess, the climate is not suitable for it over here or not enough pollination by the bees.

I was hoping to keep this till ripe but it fell of by itself. Sad!!
Some people like to cook it when it is still green and some people like to cook it when it is ripe. I like it both ways.
