In a kadai or pan, heat 1.5 tablespoon oil or ghee.
Add all the whole spices and saute them till they crackle and become fragrant.
Then add the chopped onions.
Stir often and saute till the onions turn light golden.
Then add 1 tsp crushed ginger, 1 tsp crushed garlic, 2 to 3 slit green chilies and 2 to 3 dry red chilies. Mix well and saute till the raw aroma of ginger & garlic goes away.
Add crushed kasuri methi and stir.
Now add the chopped tomatoes. Stir and saute till the tomatoes soften.
Then add turmeric powder, red chilli powder, coriander powder, garam masala powder and a pinch of asafoetida.
Mix the spice powders with the rest of the onion-tomato masala.
Add the cooked dal and mix well.
Add water and stir very well.
Season with salt and mix again.
Simmer the dhaba dal on a low flame till the dal thickens a bit.
Keep on stirring at intervals so that it does not stick to the bottom of the pan.
When the dal is done, switch off the flame. Add chopped coriander leaves. Reserve some coriander leaves for garnishing.
Garnish with some coriander leaves and serve the dhaba style dal hot with rotis or parathas or steamed rice or cumin rice or ghee rice. You can also do the dhungar method if you want and then serve the dal.
