Tender lentils slow-simmered with warming turmeric, finished with a sizzling tarka of golden ghee, roasted cumin, and fresh coriander.
Pressure cook the soaked dals with the turmeric and 3 cups water until soft, then whisk lightly.
Heat the ghee in a kadhai and splutter the cumin seeds.
Sauté the onion until golden brown, about 5 minutes.
Add the tomatoes and red chili powder and cook until the ghee separates.

Stir in the garam masala and coriander and serve hot with rice or roti.
