Boil the Dal: Pressure cook the Toor Dal and Moong Dal together with some water for 3 whistles. Mash the cooked dal until it is completely smooth.
Temper the Spices: Heat oil in a pan or cooker. Add mustard seeds, cumin seeds, and a pinch of hing to the hot oil.
Sauté Aromatics: Toss in the crushed garlic cloves, curry leaves, and slit green chillies. Fry them until the chillies look slightly blistered and the garlic turns light brown.
Add Veggies: Add the sliced onion to the pan and sauté lightly. Next, add the chopped tomato, grated ginger, and turmeric powder. Mix everything well.
Cook the Mango: Add the grated raw mango and salt to the pan. Cook this mixture for about one minute.
Mix the Dal: Pour the mashed dal into the pan. Stir everything together nicely so all the flavours combine.
Adjust Consistency: Add water to reach your desired thickness. Sprinkle in freshly chopped coriander leaves.
Simmer and Serve: Let the Kairiche Varan boil on medium heat for about 5 minutes. Add a pinch of sugar or jaggery at the very end to balance the tanginess. Your delicious Raw Mango Dal is ready to serve hot!
