Prepare the Secret Masala: In a mixer jar, add the dry coconut, green chillies, garlic, ginger, and coriander leaves. Grind without adding water to form a coarse, dry paste.
Temper the Oil: Heat oil in a pan or kadhai. Add mustard seeds and let them splutter. Then add cumin seeds, a pinch of hing, and fresh curry leaves.
Sauté Aromatics: Add the chopped onion and roast until it turns golden brown. Add turmeric powder and mix well.
Cook the Masala: Add the prepared secret masala paste to the pan. Sauté on medium heat for about 2 minutes until the raw smell disappears.
Add Tomatoes: Toss in the chopped tomatoes and cook until they soften and blend with the masala.
Add Spices: Lower the flame. Add Kanda Lasun Masala (or chilli powder), garam masala, coriander-cumin powder, and salt. Sauté for 1-2 minutes until the oil starts to separate.
Add Chickpeas: Add the fresh green chickpeas (Hirva Chana) to the pan. Mix well, coating them with the spices. Sauté for 1 minute on medium flame.
Simmer: Add warm water (adjust amount for a semi-dry/lapthapi consistency). Cover the pan with a lid.
Cook to Perfection: Let it simmer on a low flame for 15-20 minutes until the chickpeas are soft and cooked through.
Serve: Your delicious Lapthapi Hirva Chana is ready!
