Soak three cups Zeera-Samba rice in water. Zeera-Samba is also known as Chiti-Mutiyalu in Telugu.
Fry fish in mustard oil after rubbing it with some turmeric powder, coriander powder, chilly powder and salt with some ginger-garlic paste. I used Black Pomfret but you can use any fish like Indian Salmon, Sea Bass etc..
Remove the the fish and using the same oil and some butter fry four large onions.Add a couple of whole green chilies and some ginger-garlic paste. Fry till the onions are almost golden. Add a chopped tomato and salt. Keep stirring and once the oil separates add half a cup of coconut milk and half a cup of thick curd. Add the juice of a lemon. Mix them well and dilute with 5 cups of water. This combined 6 cups of liquid is for the three cups of rice we have been soaking in water.
Place the fish in the sauce and cover your pressure cooker’s lid. Do not seal it. Do not keep any weight on it. after five minutes open and stir it. Repeat one more time.
Remove the fish and add the rice. Mix in some fresh coriander. Place the fish on top of the rice. Pressure cook for one whistle on high. Then let it simmer for about 8-10 mins.
Serve Hot and enjoy your special family lunch or dinner.
