Tender lentils slow-simmered with warming turmeric, finished with a sizzling tarka of golden ghee, roasted cumin, and fresh coriander.
Pressure-cook the toor dal with turmeric and water until soft, then whisk until smooth.
Add the jaggery, tamarind paste, and salt with 1 cup water; simmer 5 minutes.
Heat the groundnut oil and crackle the mustard seeds and cumin seeds.
Pour the tadka into the dal and simmer 10 minutes until slightly thickened and balanced sweet-sour.
Serve this khatti-meethi dal hot with steamed rice.
