Another prawn dish extended this time with a root vegetable, colocasia (seppangkizhangu). Colocasia is available all over India, like the potato. When boiled they develop a slimy texture. In Tamil Nadu colocasia is combined with prawn as the sliminess acts as a thickening agent so that we don’t have to use coconut, which is quite often used in prawn preparations and is the most common thickening agent. Also, the neutral flavour of colocasia does not dominate the dish and brings out the flavour of the prawns as well as the spices used.
