Restaurant style sambar Recipe

This recipe is very close to my heart as my mother used to prepare it during my childhood. I always loved it's awesome taste. Now i prepare it for my children, the same way as my mother used to prepare it. In this recipe, instead of ready made sambar powder, coriander seeds and red chilies are fried then ground with fried onion and coconut. Fresh is always better, maybe because of this the sambar always tastes awesome and has a delicious aroma. I have named it 'restaurant style sambar'.
