Tender lentils slow-simmered with warming turmeric, finished with a sizzling tarka of golden ghee, roasted cumin, and fresh coriander.
Roast each dal separately in a heavy pan over low heat until golden and nutty, then cool.
In the same pan, crisp the dried red chilies and toast the cumin seeds until fragrant.
Grind the roasted dals, chilies, cumin, asafoetida, and salt into a slightly coarse powder.
Cool completely and keep in an airtight jar for up to a month.
Mix a couple of spoons with sesame oil or melted ghee and serve with idli, dosa, or hot rice.
