- Cover and cook for 5 minutes or until the tomatoes are soft and mushy. 
- Add in cooked toor dal and mix well. 
- Adjust the consistency, and boil for 5 minutes or until the flavour is absorbed well. 
- Now to prepare the tempering, heat 2 tbsp ghee. Add 1 tsp mustard, 1 tsp cumin, 10 cloves garlic, 2 dried red chilli, few curry leaves and a pinch hing.
