Soak the lentils in plain water for 3 to 4 hours, washing them thoroughly before and after soaking.
Heat half a ladle of oil in a pan. Once hot, add mustard seeds and let them splutter. Add cumin seeds, curry leaves, and a little asafoetida powder. You can also add a bay leaf if desired.
Add the chopped onions and saute for 2 minutes until lightly browned.
Add the ginger, garlic, green chilli, and coriander leaves paste. Saute for another minute.
Add the chopped tomato and saute for a minute.
Turn the heat to low and add salt, Kolhapuri masala, garam masala powder, and cumin-coriander powder. Mix well.
Add a little turmeric powder. Mix well.
Add a little warm water, mix, and cover the pan. Cook on medium heat for 5 minutes.
Remove the lid, stir, and add the soaked lentils. Mix well.
Add a little more warm water (just enough for a dry consistency).
Cover the pan and cook on low heat for 10-15 minutes, or until the lentils are cooked and dry.
Garnish with finely chopped coriander leaves.
