Prepare the Brinjal: Wash the brinjal and cut them into medium-sized pieces. Keep them aside.
Temper the Oil: Heat oil in a pan (kadhai). Add mustard seeds and let them splutter. Then, add cumin seeds, curry leaves, and a pinch of hing.
Sauté Onion: Add the finely chopped onion to the pan. Sauté well until it turns golden brown.
Add Special Paste: Add the crushed ginger-garlic-coconut-chilli mixture. Roast this for about 1 minute until the raw smell disappears.
Cook Tomatoes: Add the chopped tomato and salt. Sauté for another minute until the tomatoes soften.
Add Spices: Lower the flame and add Kanda Lasun Masala, turmeric, coriander-cumin powder, and garam masala. Mix well.
Add Brinjal: Add the chopped Vangi pieces to the pan. Stir well to coat every piece with the masala. Cook for 1-2 minutes.
Add Peanut Powder: Sprinkle the roasted peanut powder over the vegetable and mix. This adds a nutty flavour and thickness.
Simmer: Pour in 1.5 bowls of warm water to get that perfect "Lapthapi" (semi-thick) consistency.
Cook to Perfection: Cover the pan with a lid. Cook on low heat for 10-15 minutes. Stir once in between to prevent sticking.
Serve: Once the oil separates and the brinjal is soft, your Spicy Brinjal Curry is ready!
