Andhra Fish Curry
Ingredients:
1 kg fish cubes( curry cut)
1 cup finely chopped onions(a mixture of large and small)
6 slit green chillies
a dollop of fresh ginger garlic paste
Dry roast and grind a fistful each of cumin seeds,coriander seeds, dry red chillies
1/2 tsp turmeric pwd
10-12 curry leaves
1 big lemon-sized tamarind pulp (soak tamarind in 1 1/2 cup of warm water and extract thick juice)
2 tbsp chopped fresh coriander leaves (optional)
salt to taste
1/2 cup oil

Tempering:
1 tsp mustard seeds
1/2 tsp methi seeds (fenugreek)

Heat oil in a thick bottomed wide vessel and add the mustard seeds and let them splutter.Add the methi seeds and let it brown.Add the curry leaves and stir for a few seconds.
Add the chopped onions and fry on medium heat till the onions turn transparent. Add ginger-garlic paste and fry for 3 mts. Add the turmeric pwd and ground powder mix and salt and fry for a minute. Add the tamarind extract and bring it to boil. I also added a tbsp of sakthi fish curry masala to enhance the taste.
Now carefully place the fish pieces in the vessel and cook covered for 3 mts. Add the green chillies. Turn the fish pieces over and cook. Cover and cook on low heat for 10 mts. Let the sauce thicken and till the oil separates or leaves. Adjust salt and garnish with chopped coriander leaves.

Note: Do not stir too much lest the fish pieces break and be gentle while stirring the fish pieces. Serve it after a couple of hours of cooking so that the fish pieces absorb the tangy flavour of the tamarind sauce and spices.
By the way, once you clean the fish, add some crystal salt and turmeric and leave aside for few mins
