Masor Boror Tenga
A classic Assamese sour fish curry featuring a light, tangy tomato gravy and savory fish and lentil fritters. This dish, known as 'tenga,' offers a unique and refreshing flavor profile, perfect with steamed rice.
For 4 servings
Prepare the Fish and Lentils
- In a small pot, add the fish pieces with a pinch of salt and turmeric. Add just enough water to cover and boil for 8-10 minutes until cooked through.
- Drain the fish, let it cool slightly, then carefully remove all bones and skin. Mash the fish flesh with a fork and set aside.
- Drain the soaked masoor dal completely. Using a grinder, blend it into a coarse paste without adding any water. A slightly grainy texture is ideal.
Make the Fritter (Bor) Batter
- In a mixing bowl, combine the mashed fish, coarse dal paste, finely chopped onion, ginger-garlic paste, the 1 chopped green chilli, 2 tbsp of coriander leaves, 1/4 tsp turmeric powder, rice flour (if using), and 1/2 tsp salt.
- Mix thoroughly until all ingredients are well incorporated to form a thick, sticky batter.
Fry the Fish Fritters
- Heat the mustard oil in a kadai or deep pan over medium heat until it's hot but not smoking.
- Carefully drop small, flattened spoonfuls of the batter into the oil. Do not overcrowd the pan; fry in batches.
- Shallow fry for 3-4 minutes on each side, until they are golden brown, crisp, and cooked through.
- Remove the fried fritters with a slotted spoon and place them on a paper towel to drain excess oil. Set aside.
Prepare the Curry (Tenga) Base
- Remove excess oil from the pan, leaving approximately 2 tbsp.
- Reheat the oil over medium heat. Add the panch phoron seeds and let them crackle for about 30 seconds until fragrant.
- Add the 2 slit green chillies and sauté for another 30 seconds.
Cook the Tenga Gravy
- Add the tomato puree, the remaining 1/2 tsp of turmeric powder, and 3/4 tsp of salt. Sauté for 5-7 minutes, stirring occasionally, until the raw smell of the tomatoes disappears and oil begins to separate at the edges.
- Pour in 4 cups of water, stir well, and bring the gravy to a rolling boil.
Combine and Finish the Dish
- Once the gravy is boiling, gently slide the fried fish fritters into it.
- Reduce the heat and simmer for just 2-3 minutes. This allows the fritters to absorb the tangy gravy without becoming soggy or breaking apart.
- Turn off the heat completely. Stir in the fresh lemon juice and the remaining 2 tbsp of chopped coriander leaves.
- Let the curry rest for 5 minutes before serving hot with steamed white rice.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most authentic flavor, use pungent mustard oil for both frying and cooking the curry.
- 2The consistency of the dal paste is key. It should be thick and coarse. If it's too watery, the fritters will not hold their shape.
- 3Do not over-simmer the fritters in the gravy, as they can disintegrate. A brief 2-3 minute simmer is sufficient.
- 4Always add lemon juice after turning off the heat to preserve its fresh aroma and prevent the curry from turning bitter.
- 5The 'tenga' gravy is meant to be thin and soupy, not thick. Resist the urge to add any thickening agents.
- 6Adjust the sourness to your liking. You can add more or less lemon juice as desired.

Souring Agent
Instead of tomatoes and lemon, use traditional Assamese souring agents like sliced Elephant Apple (Outenga), sour roselle leaves (Tenga Mora), or the juice of Kaji Nemu (Assam lemon).
Vegetarian VersionVegetarian Version
Omit the fish entirely. Make plain masoor dal fritters (bor) and add them to the same tangy tomato gravy for a delicious vegetarian alternative.
Different FishDifferent Fish
Instead of making fritters, you can use pan-fried pieces of fish like Rohu or Catla. Add the fried fish pieces to the boiling tenga gravy and simmer for 4-5 minutes.
Why this is on our healthy list.
Rich in Lean Protein
The combination of fish and masoor dal provides a high-quality source of lean protein, which is essential for muscle repair, immune function, and maintaining satiety.
Supports Heart Health
Freshwater fish like Rohu are a good source of Omega-3 fatty acids, which are known to reduce inflammation and support cardiovascular health. The use of mustard oil also contributes beneficial monounsaturated fats.
Aids Digestion
The 'tenga' or sour profile of the dish, derived from tomatoes and lemon, is traditionally believed to stimulate digestive enzymes, improve appetite, and promote gut health.
Anti-inflammatory Properties
Key spices used in the curry, such as turmeric (containing curcumin) and ginger, possess natural anti-inflammatory and antioxidant properties that help combat oxidative stress in the body.
