Aviyal is a traditional dish of the South Indian state of KERALA. This is a stew made of a variety of vegetables coconut and yoghurt. This is one dish that is mandatory while serving sadya (traditional celebration meal) along with saambaar, rasam, thoran etc. In the northern part of Kerala this dish is made with yoghurt but in the southern part it is cooked with tamarind juice. Both ways it is just plain yummy!!
