Wash 2 cups of basmati rice or seeraga samba rice in water 3 or 4 times or until the water is clear and set aside.
In a pan add water and start cooking. To the water add the whole spices. Add in salt and oil and bring everything to a boil.
Once the water starts boiling add the soaked rice and cook until the rice is 95 % cooked. Switch off the stove and let it rest for 5 mins.
Drain the excess water and then spread the cooked rice on a wide plate and let it cool.
Prepare the prawn Masala
Heat a biryani pot with oil. Once it heats up add in fennel seeds and then Bay leaves, Cinnamon sticks, Cloves, and Cardamom. Let it splutter.
Then add in sliced onions and Saute until the onions are soft.
Next, add in the chopped tomatoes and cook till they become soft.
Next, add ginger garlic paste and fry till the raw smell leaves.
Add Mint and coriander leaves, Saute for a min or till they shrink.
Now add the spice powders. I am using Chilli powder, Garam Masala, Turmeric powder, and Salt. Mix well and cook for a min.
Now add in the curd/ yogurt.
Combine and cook till the oil separates, Add Lemon Juice and Kewra water if using.
finally, add the cleaned Shrimp/ Prawns and combine them with the masala. Cook for 5 mins and switch off the flame.
Layer the Biryani
In a bowl add milk and Saffron. Let it rest for 30 mins. Chop Coriander leaves and keep them ready as well. Fry onions, Cashew nuts and keep them ready as well.
On top of the prepared biryani masala, spread half of the cooked rice.
Top it with saffron milk, Chopped coriander leaves, fried onions, and fried cashew nuts.
Top it with the remaining rice. Sprinkle in saffron milk, coriander leaves, fried cashew nuts, and fried onion. Close the biryani pot. I used my Dutch oven.
Switch on the stove to a very low flame and then place an iron dosa pan or a heavy iron pan and then place the biryani pot on top. Cook in the lowest flame for 15 mins and switch off.
Let the pot remain closed for another 30 mins and then open it.
Gently fluff the rice. Delicious Prawn biryani is now ready.
Notes
Use very good quality Basmati Rice. Soak for about 25-30 mins before you start cooking
