Duck Curry with Kumura (Kumura Diya Haah Mangxo) is a legendary and deeply comforting delicacy from Assamese cuisine, cherished for its rich flavors and cultural significance. This traditional dish features succulent duck meat slow-cooked with tender ash gourd (kumura or wax gourd), allowing the vegetable to absorb the savory richness of the meat while adding a subtle sweetness and delicate texture. Generously seasoned with freshly ground black pepper and aromatic spices, the curry develops a robust, warming flavor that is especially prized during the cooler months. A beloved centerpiece of Assamese festive feasts, Kumura Diya Haah Mangxo is traditionally enjoyed during winter and celebrated occasions such as the harvest festival of Bhogali Bihu, where it symbolizes hospitality, abundance, and the region’s rich culinary heritage.

Wash the duck pieces thoroughly. In a large bowl, combine the meat with half of the ginger-garlic paste, half of the turmeric powder, half of the cumin powder, 1 tablespoon of mustard oil, and salt. Mix well and set aside for 30 minutes.
Heat 4 tbsp of mustard oil in a heavy-bottomed kadai or pressure cooker until smoking. Add whole spices and sliced onions, frying until golden brown. Add the marinated duck and fry on medium heat for 6–7 minutes to release the natural oils.
Add the remaining turmeric, cumin, coriander, and black pepper powder. Stir well, cover, and cook on low flame for 10–15 minutes until the fat separates. If it sticks to the bottom, splash a tiny amount of warm water.
Once the duck is semi-tender, add the diced ash gourd (kumura) to the pot. Toss it with the meat for 3–4 minutes.
Add 1 to 1.5 cups of warm water (depending on how much gravy or jhul you prefer). If using a pot, cover and simmer on low flame for 30–45 minutes until both the meat and gourd are meltingly tender. (If pressure cooking, cook for 3–4 whistles on medium heat).
Sprinkle garam masala and give it a final stir. Serve piping hot with traditional warm sticky rice or steamed Joha rice.
