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 2 cups water until soft and mash lightly.
Boil the squeezed tamarind extract with the shallots, sambar powder, and salt for 10 minutes until the shallots soften and the raw smell is gone.
Add the mashed dal with 1 cup water and simmer for 8 minutes until slightly thickened.
Heat the gingelly oil, crackle the mustard seeds, fenugreek seeds, and curry leaves, pour over the sambar, and serve with rice, idli, or dosa.
