For preparing Andhra Fish Pulusu, first soak tamarind in 3 cups of warm water.
Grind onions to paste.
Cut the fish into medium pieces. Use fish like tilapia or porgees.
Heat a Mud Pot and spread oil (10 tbsp looks too much but fish pulusu needs lot of oil).
Add Curry Leaves, Whole Green Chillies (if you need more spiceness for the curry while eating, break the green chillies) and fry it for few minutes.
Add Onion Paste, Turmeric Powder, Salt and mix it. Fry it for around 7 mts so that onion paste is cooked well.
Add Garlic Paste, mix and fry it for few minutes until the raw smell goes away.
Add Chilly Powder and fry it for few minutes.
Add tamarind water(2 cups) and mix well. Let it boil.
Add Hot Water(1 or 2 cups), curry shouldn't be very watery.
Close with lid and let it boil for 7 minutes.
Add fish and mix it. Check the sourness before you add the fish. Add more tamarind water if needed. Close the lid and cook it for 10 minutes.
Add Garam Masala, Corriander Leaves, and mix it without breaking fish.
Close the lid and cook for 5 mts.
Enjoy Andhra Fish Pulusu with hot rice. It tastes even better the next day.
