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 2 cups water until soft and whisk smooth.
Boil the shallots, tamarind pulp, sambar powder, salt, and 1.5 cups water for 10 minutes until the shallots soften.
Add the whisked dal and simmer 5-7 minutes until slightly thickened.
Heat the oil, pop the mustard seeds and curry leaves, and pour over the sambar.
Serve hot with dosa, idli, or steamed rice.
