Clean and wash the prawns. Then add turmeric powder and salt to it
Mix them well with the prawns. Now heat a pan and add some oil in it. Gradually add the prawns in it. Fry them well and then remove them in a plate & keep them aside.

Then take a fresh pan; you can even take a pressure cooker, add some ghee and oil in it. Once it gets heated, add the khada masalas mentioned above like a bay leaf, cinnamon stick, dried red chillies, peppercorns, green cardamom and some cloves. Let them splutter then add some onion slices in it. Cook until it becomes little tender.

Then add ginger-garlic paste to it. Mix it and fry them for about a minute. Then add some salt and turmeric powder. Mix them well & cook it for 2 more minutes on a low flame.

Then add chopped tomatoes in it. Fry them well until oil starts releasing from the masala. I have fried the masala in a pan & then added it into the pressure cooker but you can directly cook it in cooker.

Now take a pressure cooker, add some ghee in it. Once it becomes hot, you can repeat the khada masalas but I have skipped them. I've directly added the rice to it. Fry the rice on a low flame until it becomes pure white in colour. Then add the masala in it. (mentioned in step 4 above) Mix everything well.

Then add the water accordingly and add the fried prawns too. (mentioned in step 1). Combine everything well then add sugar, little turmeric powder and some salt as per your taste. Give it a good mix.
