Boil this dal for at least ½ hour. Keep adding water and mixing at intervals to keep it from sticking to the bottom of the pan.
Add the garam masala and the cardamom powder to the dal and mix well.
Make a tempering of 1 tsp of oil, 1 tsp of cumin seeds, 1 dry red chilli, 1 pinch of asafetida. When the cumin seeds have crackled add 1 tsp of chilli powder and take it off the fire. Add immediately to the dal.
