For 4 servings
Prepare Lentils and Duck
- Wash the matir dail (black gram lentils) thoroughly under running water. Soak them in ample water for at least 4 hours, or preferably overnight.
- Clean the duck pieces well. In a mixing bowl, marinate the duck with 1/2 tsp turmeric powder and 1/2 tsp salt. Mix well to coat and set aside for at least 20 minutes.
Cook the Lentils
- Drain the soaked lentils. Transfer them to a pressure cooker.
- Add 2 cups of fresh water and 1/2 tsp of salt. Secure the lid.
- Pressure cook on medium heat for 2-3 whistles, which should take about 10-12 minutes. The lentils should be soft but still hold their shape. Do not overcook them into a mush. Set aside.
Sauté the Aromatics
- Heat mustard oil in a heavy-bottomed pan or kadai over medium-high heat until it just begins to smoke. This step is crucial to remove the oil's raw pungency.
- Reduce the heat to medium, add the sliced onions, and sauté for 8-10 minutes, stirring frequently, until they are soft and golden brown.
- Add the ginger paste and garlic paste. Sauté for another 2 minutes until their raw aroma disappears.
- Add the remaining 1/2 tsp turmeric powder, Kashmiri red chili powder, cumin powder, and coriander powder. Stir for 30-40 seconds until the spices are fragrant.
Cook the Duck
- Add the marinated duck pieces to the pan. Increase the heat to high and sear the duck for 5-7 minutes, turning occasionally, until browned on all sides. This helps to render some fat and build deep flavor.
- Add the remaining 1 tsp of salt and the slit green chilies. Mix everything well.
- Pour in 2 cups of hot water. Bring the mixture to a boil, then reduce the heat to low. Cover the pan with a tight-fitting lid.
- Let the duck simmer for 45-50 minutes, or until it is about 80% cooked and tender. Stir occasionally to prevent sticking.
Combine and Finish
- Pour the cooked lentils, along with their cooking liquid, into the pan with the duck curry. Stir gently to combine.
- Bring the curry back to a simmer and cook, uncovered, on low heat for another 15-20 minutes. This allows the flavors to meld and the gravy to thicken to the desired consistency.
- Check the seasoning and add more salt if needed.
- Sprinkle the garam masala powder over the curry and give it a final stir.
- Garnish with freshly chopped coriander leaves. Let the dish rest for 10 minutes off the heat before serving hot with steamed rice.
