Ou Tenga Mutton Curry
A classic Assamese delicacy, this mutton curry gets its signature tangy flavor from Ou Tenga (elephant apple). Tender mutton pieces are slow-cooked in a light, aromatic gravy, creating a uniquely sour and savory dish that is a staple in Assamese households.
For 4 servings
Prepare the Elephant Apple (Ou Tenga)
- Wash the Ou Tenga thoroughly. Cut it into 4-5 large pieces.
- In a small pot, combine the Ou Tenga pieces with 1 cup of water. Bring to a boil.
- Cook for 10-12 minutes over medium heat until the pieces are soft and tender.
- Remove from heat and let it cool completely. Lightly mash the boiled pieces with the back of a spoon. Reserve the water it was boiled in.
Marinate the Mutton
- In a mixing bowl, combine the mutton pieces with 1/2 teaspoon of turmeric powder and 1/2 teaspoon of salt.
- Mix well with your hands to ensure all pieces are evenly coated.
- Set aside to marinate for at least 15-20 minutes.
Sauté Aromatics and Brown the Mutton
- Heat mustard oil in a pressure cooker over medium-high heat. Wait until it becomes pungent and you see light smoke.
- Carefully add the bay leaves and sliced onions. Sauté for 6-8 minutes, stirring frequently, until the onions are soft and golden brown.
- Add the ginger and garlic paste. Cook for 1 minute until the raw aroma disappears.
- Add the marinated mutton pieces to the cooker. Sauté for 8-10 minutes, turning the pieces, until they are well-browned on all sides. This step is crucial for developing flavor.
Pressure Cook the Curry
- Add the remaining 1/2 teaspoon of turmeric powder, slit green chilies, and quartered potatoes. Stir for 30 seconds.
- Add the mashed Ou Tenga along with its reserved cooking water.
- Pour in the remaining 3 cups of water and add the remaining 1 teaspoon of salt. Stir everything well to combine.
- Secure the lid of the pressure cooker. Cook on high heat until the first whistle. Then, reduce the heat to medium-low and cook for 20-25 minutes (or for about 5-6 whistles).
- Turn off the heat and allow the pressure to release naturally. This can take 10-15 minutes.
Finish and Serve
- Once the pressure has fully released, carefully open the lid.
- Check if the mutton is tender. If not, you can pressure cook for another 1-2 whistles.
- If the gravy is too thin for your liking, simmer the curry without the lid for 5-7 minutes to thicken it slightly.
- Check for seasoning and adjust salt if needed.
- Garnish with freshly chopped coriander leaves and serve hot with steamed rice.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Using mustard oil is key to the authentic Assamese flavor; avoid substituting it if possible.
- 2Browning the mutton thoroughly before adding water is essential for a deep, rich flavor in the final curry.
- 3Don't over-mash the Ou Tenga. You want some texture and a gradual release of its sourness into the gravy.
- 4This curry tastes even better the next day as the flavors meld and deepen overnight.
- 5If you cannot find Ou Tenga, you can use raw mango or tamarind pulp for a tangy flavor, though the authentic taste will differ.
- 6Allowing the pressure cooker to depressurize naturally helps in making the mutton more tender.
