Prep the Dal: First, make sure your matki dal has been soaked in plain water for at least two hours. After soaking, drain the water and wash the dal well.
Start the Tadka: Heat oil in a pressure cooker (or a kadai). Once hot, add the mustard seeds. When they pop, add the cumin seeds, asafoetida, and curry leaves.
Sauté Aromatics: Add the finely chopped onion and sauté until it becomes light and translucent. Now, add the ginger-garlic-green chilli paste and cook for another minute until the raw smell is gone.
Add Spices: Add the turmeric powder and the chopped tomato. Cook for a minute until the tomato starts to soften.
Add Masala: Lower the heat and add the Kanda Lasun Masala and salt to taste. Mix everything well.
Add Dal: Add the soaked and drained matki dal to the cooker. Stir everything together gently to coat the dal with the masalas.
Cook the Dal: Add a handful of fresh coriander and mix again. Now, add just a little warm water—less than half a glass is enough, as we want a dry bhaji.
Pressure Cook: Secure the lid of the pressure cooker. Cook on a low flame for two whistles. (Since the dal is well-soaked, it cooks very quickly).
Rest and Serve: Turn off the gas and let the pressure release naturally. Open the lid, and your Matki Dal Sukhi Bhaji is ready! Garnish with more fresh coriander before serving.
