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 1 cup water until very soft and whisk it smooth.
Coarsely crush the peppercorns, 1 tsp cumin seeds, and 1 dried red chili.
Heat ghee, pop the mustard seeds, remaining cumin seeds, remaining red chili, and asafoetida.
Add 1.5 cups water, the ground powder, whisked dal, and salt, and simmer until frothy.
Off the heat, stir in the lemon juice and serve as a soup or with steamed rice.
