Paruppu arisi sadam is one of the lunch specials in Coimbatore. While i was doing my UG in Coimbatore my friends use to bring this rice for lunch which tasted very good. We r from Chennai ,so my mother didn't know how to make it. After marriage, I came to know this is one of my mother in laws speciality!!!. I found out the recipe and started making it by my own!!!
1/2 tsp Cumin seeds
