Irumban puli in English is known as tree sorrel or cucumber tree. In India, it is known as bilimbi, irumban puli, chemmeen puli, bimbul, orakkaapuli, bimblin etc.
The tree bears quite a lot of fruits. It is very sour in taste. It can be eaten raw with salt and chilli powder. Since it is very tangy in nature, it is added to some dishes substituting for tamarind or tomato. It is used in sambar or fish curry or made into pickles.
Mostly, we used to make pickle out of it. One of my colleague has got the tree in her building and she shared me with this fresh fruit. I also made subzi out of this and was quite tasty.
