Keep the rice soaked in water, until it is ready to be added to the pressure cooker.
Heat oil or butter or ghee in a pressure cooker.
Saute ginger and garlic paste.
Add onion and saute well.
When onion turns golden, add chilly powder, coriander powder, turmeric powder, cloves, cardamom and cinnamon(whole or powder) and saute.
Add tomato and crushed green chillies and saute.
Add curd or lemon juice to this mixture and mix well.
Add salt.
Add chicken pieces and mix well.
Cover the pressure cooker with a lid and cook the chicken for 5 mins on medium-high heat.
:- 5 mins is enough for broiler broiler chicken to be half cooked. I am assuming that chicken is half cooked by doing this, allowing the rest of the cooking to happen with cooking rice under pressure.
Drain the rice and keep it aside, while chicken is getting cooked.
Now open the cooker and add mint leaves, coriander leaves, roasted cashew nuts, drained rice, rose essence and mix well.
Add 1 1/2 cup of water and mix well again.
:- For 1 cup of rice, add 1 1/2 cups of water.
:- Check the level of salt and add, if reqd.
Cover the pressure cooker with its lid.
Put the pressure regulator weight on the lid.
Pressure cook upto 1 whistle.
Open the cooker and give a gentle stir.
Instant Biriyani is ready.
