Soak the urad dal for two hours and grind into a thick and coarse paste. Chop the chillies and curry leaves very finely. In a kadai, add the remaining sesame oil and pop the mustard seeds. When done, add asafoetida and coconut. After stirring for a minute add the urad dal paste and salt. Mix well, and cook covered in a low flame till urad dal paste is cooked well. Remove from stove and when cooled down crumble into small pieces so it is not clumpy.
In a large mixing bowl, add the rice, cooked and crumbled urad dal, grated carrots, chopped coriander, lemon juice and salt as needed. Mix well and you now have a nutritious and tasty salad that is a complete meal in itself. Serves 4.
