Assamese Fish Curry
A light, tangy fish curry from Assam, known as 'Masor Tenga'. This authentic recipe features a thin, soupy broth flavored with panch phoron and mustard oil. The sourness from tomatoes and lemon juice makes it a refreshing and simple dish, perfect with steamed rice.
For 4 servings
Marinate the Fish
- Rinse the fish pieces under cold water and pat them completely dry with paper towels.
- In a mixing bowl, gently rub the fish with 1/2 tsp of turmeric powder and 1/2 tsp of salt, ensuring all sides are coated.
- Set aside to marinate for 15 minutes.
Shallow Fry the Fish
- Heat the mustard oil in a wide pan or kadai over medium-high heat. Wait until it becomes very hot and you see faint smoke rising; this mellows its pungent flavor.
- Carefully slide the marinated fish pieces into the hot oil. Do not overcrowd the pan; fry in batches if necessary.
- Fry for 2-3 minutes on each side until they are light golden brown and slightly crisp. Do not overcook.
- Using a slotted spoon, remove the fish and set aside on a plate.
Prepare the Curry Base (Tadka)
- In the same pan with the remaining oil, lower the heat to medium.
- Add the panch phoron seeds. Allow them to crackle and become fragrant, which takes about 30 seconds.
- Add the slit green chilies and sauté for another 15-20 seconds.
- Add the finely chopped onion and cook for 4-5 minutes, stirring occasionally, until it becomes soft and translucent.
Cook the Masala
- Add the ginger-garlic paste and cook for 1 minute until its raw smell disappears.
- Stir in the tomato puree, the remaining 1/2 tsp turmeric powder, red chili powder (if using), and the remaining 1 tsp salt.
- Mix well and cook the masala for 6-8 minutes, stirring frequently. The masala is ready when it darkens in color and you see oil separating at the edges.
Simmer the Curry
- Pour in 2.5 cups of warm water and stir to combine with the masala. Increase the heat and bring the gravy to a rolling boil.
- Once boiling, gently place the fried fish pieces into the gravy.
- Reduce the heat to a low simmer, cover the pan, and let the curry cook for 7-8 minutes. This allows the fish to absorb the flavors of the broth.
Finish and Serve
- Turn off the heat. Stir in the fresh lemon juice.
- Garnish with freshly chopped coriander leaves.
- Let the curry rest for at least 5 minutes for the flavors to meld before serving.
- Serve hot with steamed rice, preferably Joha rice for an authentic Assamese meal.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most authentic flavor, do not substitute mustard oil. Always heat it until it's slightly smoking to mellow its pungent taste.
- 2Be gentle when handling the fish during frying and simmering to prevent it from breaking apart.
- 3This curry is meant to be a thin, soupy broth ('jool' or 'tenga'). Avoid the temptation to thicken it or over-reduce the gravy.
- 4Add the lemon juice only after turning off the heat to preserve its fresh, tangy flavor and aroma.
- 5Patting the fish completely dry before marinating helps it fry better and prevents oil from splattering.

Authentic Souring Agent
For a more traditional Assamese taste, replace tomatoes and lemon juice with 'outenga' (elephant apple) or 'thekera' (dried mangosteen). Soak a few pieces of thekera in warm water and add the water and pieces to the curry.
Add VegetablesAdd Vegetables
You can add potato wedges or bottle gourd (lauki) pieces to the curry. Add them after sautéing the onions and cook until they are partially tender before adding the water.
Mustard Paste VersionMustard Paste Version
For a different flavor profile, add 2 tablespoons of freshly ground mustard seed paste ('horiyoh') along with the tomato puree. This creates a more pungent and thicker gravy.
