Tender lentils slow-simmered with warming turmeric, finished with a sizzling tarka of golden ghee, roasted cumin, and fresh coriander.
Pressure-cook the dal with turmeric and 3 cups water until soft; whisk smooth with more water to a pourable consistency.
Stir in the jaggery, red chili powder, and salt; simmer 10 minutes.
Heat the ghee; crackle the mustard seeds, cumin seeds, and asafoetida.
Pour the tempering over the dal and simmer 5 minutes.
Add the lemon juice for the classic sweet-sour finish and serve with steamed rice.
