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 it smooth.
Boil the tamarind pulp with 1 cup water, shallots, salt, and sambar powder for 10 minutes until the shallots soften.
Add the mashed dal with extra water as needed and simmer 10 minutes until the sambar slightly thickens.
Heat oil and pop the mustard seeds and curry leaves.
Pour the tadka over the sambar, cover, and rest 5 minutes before serving hot with rice.
