Sour Fish Curry (Maasor Tenga)

Assamese Food
Sour Fish Curry with Fried Curry Banana & Rice

So summer’s here and being a weekend I thought of making the famous Assamese Sour Fish Curry, also called, Maasor Tenga for lunch. Now, this is a very popular dish made in all the homes across Assam. It’s light with very few ingredients and the magic ingredient being lemon juice, just perfect for the summer. Being from a place which is surrounded by the mighty Brahmaputra River, my fish recipes tend to be more suited towards river fish. And, I used some Rohu Fish for this.

I paired this dish with some Curry Banana Chips and Rice. I just mixed the chips with some salt and turmeric and went ahead and deep fried it in mustard oil.

Fish – 400 gms, curry cut

Mustard Oil – 4-5 tbs

Turmeric – 1 tsp

Black Cumin/Kala Jeera – 1/2 tsp

Garlic – 4 large cloves, finely chopped

Potatoes – 2 small, peeled, cut into halves & thinly sliced

Lemon – 1 or 1/2, depending on the sourness you prefer

Coriander for garnish, freshly chopped

Salt to taste


First, marinate the fish with 1/2 a tsp of turmeric and a little bit salt. Heat the mustard oil till the strong smell of mustard leaves the oil. And I fried the fish pieces in two batches.

Note: You just need to half cook the fish as it will cook again once we get the curry ready.

Once both batches are done, throw in the potatoes in the same oil. Add the black cumin, turmeric, half of the chopped garlic and a little salt and fry for 3 mins with the lid on in medium-low flame.

Once it’s slightly cooked, add the rest of the garlic and pour some hot water and once again, close the lid for 6-8 mins till the potatoes are cooked. And, that’s when you take a masher and mash in the potatoes roughly which would give the curry some body.

Note: Always use hot water when you have to add water in already cooked ingredients.


Then, pour in some more hot water and once the water start boiling, add in the fried fish and add salt as required. Once, the curry boils for a bit, squeeze in some generous amount of lemon to give it the right twist.


Garnish with some freshly chopped coriander.
