Siru Kizhangu is one of my favourite vegetable. We love the flavour and aroma of this root tuber. Siru kizhangu is a seasonal root which you will get only in the month of December and January. Cleaning the siru kizhangu is the most painful part of cooking siru kizhangu. I usally soak this in the water for some time (15-30 mins) and rub it on the hard surface to clean it . Then I would remove the skin, clean it again in the water and cut it into smaller pieces. Too much for this tuber.. :-). But, as this vegetable is seasonal and I cook this very occassionaly, i really dont mind the labours process. In malayalam this vegetable is called Koorkai and keralites used to make different recipes out of this vegetable. But, i used to cook Siru kizhangu fry only and the recipe is given below.
