Clean and wash both the yellow dals 3-4 times. Add enough water and soak the dals together for 30 minutes. Add both the dals to the pressure cooker along with green chilies, turmeric, salt and 3½ cups water.
Close the lid and pressure cook the dals for 5-6 whistles on medium heat or until they are softened. Let pressure release naturally.
Open the pressure cooker and check, if the dal is too thick then you can add more water as per the consistency you require.
Switch on the heat and bring the dal to a boil.
Meanwhile, we will prepare the tadka (tempering). Heat the ghee in a small pan, add mustard seeds, cumin seeds and allow it to crackle.
Add ginger and fry for 30 seconds. Then, add slit green chilies, dried red chilies, hing and fry for 15 seconds.
Now, add kasuri methi , mix and switch off the heat. Immediately add red chili powder, mix and add the tempering to the boiling dal.
Add lemon juice and simmer the dal for another 2-3 minutes.
Dish out and garnish it with green coriander leaves.
Serve hot with steamed rice, pickle, papad and salad on side.
