Marinate mutton with the ingredients mentioned above. Keep it aside. (Or you can marinate the mutton and keep it overnight in the refrigerator. Take it out before starting cooking so it comes to room temperature.)
Wash and soak the Basmati rice.
Thinly slice onions and tomato.
Switch on the Instant Pot to saute mode. Add the ghee, when the ghee is hot, add the whole spices.
Add onions and fry them till light brown, add the tomato, when they turn soft, add the marinated mutton.
Mix it well. Close the Instant Pot and cook on high pressure for 8 minutes.
Once it is done, open the Pot. Check how much gravy is in the Pot. Add drained rice on top along with salt and lime juice.
DO NOT MIX, just spread the rice on top.
Add water as required. I added only 1 cup of water as there were 2 cups of gravy in the pot. DO NOT MIX
Close the Instant Pot and cook on high pressure for 4 minutes.
Once your Instant Pot beeps after the 4 minutes, press cancel. Set a timer for 10 minutes, after the 10 minutes quick release the pressure and open the Instant Pot.
Mix the Biriyani gently and transfer to a serving dish immediately.
Garnish with fried onions and chopped cilantro.
