Wash the pulses in water throughly and soak them in water overnight. Drain the water the next day and set the bloomed pulses aside
Heat a pressure cooker, or a pan, with 2 tablepoons of the ghee. Once hot, add the onions and fry until they turn pink and soft
Add the ginger, chillies and half of the chopped garlic. Cook for 2-3 minutes
Next, add the diced tomato and when it softens, add all powdered spices along with the salt, except the kasuri methi
Fry the spices on a low flame for a minute and then add the pulses
Stir well with the spice mix and then add 2 cups of water. Mix again, cover and pressure cook until done. If using a pan, cover and cook until the dals soften
Once the pressure in the cooker settles, open and check for the consistency of the dal - it should not be runny
If so, then simmer, without the lid on, until you achieve a semi thick consistency
Heat a separate small pan and heat the remaining ghee. When hot, add the cumin seeds
Once they crackle, add the chopped garlic, the chopped tomato and the dried chilis. When the garlic gets some colour on it, pour the tempered ghee over the cooked dal
Finally add the kasuri methi and mix
Garnish the green mung dal tadka with coriander leaves and serve hot with rotis or rice. Enjoy!
