I like to use Tilapia fish with this recipe.My mom likes Pomfret.
My Andhra friend actually makes a similar thing but with green mangoes in it , which was delicious. I will ask her for the recipe.
Ingredients
Tamarind Juice
1/4 Spoon Tumeric powder
1/4 Teaspoon salt (add more if you need to)
Grind
4 Dried Red Chillies (depends on how hot you want to Curry)
2 Teaspoon Cumin Seeds
6 Peppercorns
15 Small Onions (shallots)
Put all the things under label Grind into mixie and make it into a paste.
Note: If you dry fry the Grinding ingredients , it make it tastes sooooo much better.
In a Pan, put 8 Tablespoons of gingerly Oil (it's a lot , but it needs it), and paste, tamrind and tumeric and fry for 2 minutes. Add the Fish and put it on high head for 2 minutes, and then low simmer for the next 10 minutes. At last add the salt and 2 tablespoon of gingerly oil on top of the gravy and mix gently.
Also, this method is used to make Valaipoo Kolambu.
In a pan put the Valaipoo strands (make sure you take out the stigma and just have the strand), boil it in a little yogurt. Use the above method and where you put the fish in, put the valaipoo instead.
