Prep One
Take a heavy bottomed pan and add in all the spices. Dry roast on a low flame till the spices are slightly aromatic. Remove from the pan and set aside to cool. Once cool, Transfer the contents to a small mixie jar. Grind to a powder. 

Prep Two 
Heat oil in a pan and add in the ginger, garlic, green chillies and onions. Saute for a few minutes. Let the veggies slightly char here and there.
Add all the greens and cook for a couple of minutes. Palak in a biryani may be a first for a lot of people but trust me, it works 🙂 Remove the mixture from heat once the greens are wilted. Set aside to cool. Grind the sauteed veggies to a fine paste. Set aside.

Now lets make the biryani.

Heat ghee and oil in a pan and add in all the whole spices. Saute for a few seconds. Add the finely chopped onions to the pan. Saute the onions for a couple of minutes. Add the turmeric powder and kasuri methi. Saute for a few seconds.
Add the green masala paste that we prepared earlier. Wash the mixie with about a quarter cup of water and add back to the pan. We do not want to waste the green gold masala that we made from scratch.
Add the chicken and the salt. Bone in chicken is always preferred as the bone imparts a lot of flavour to the biryani and keeps the meat juicy and soft. Mix well so all the chicken pieces are well coated in the masala. Whisk the curd in a bowl. Always whisk the curd before adding so it does not clump up in bits. Add the whisked curd to the pan. Mix well to combine.
Cover the pan with a lid and cook on a low flame for about 10 minutes. Mix well in-between once or twice so the masalas do not scorch at the bottom.  At this stage, add the prepared masala powder. Add the lime juice.
Take the chicken pieces out to a plate and measure the liquid left in the pan. Add the chicken pieces back. Add the water as required. For every cup of rice we add, we will need two cups of liquid (water + chicken cooked water in pan). Let it all come to a boil.
Soak the rice for around 30 minutes. After soaking, completely drain the rice. Add the rice once the pot is boiling. Mix well. Let it all come to a boil again.
The cooking of the biryani and “dum” can be done in two ways. I like the OTG method as its fool proof and comes perfect every single time without the rice scorching at the bottom or the rice going mushy. 
Stovetop Method:
Once it begins to boil, cover with a lid and cook on medium heat for 3–4 minutes. Open the lid, gently stir from the bottom, cover again, and reduce the heat to low. Simmer for 10 minutes. Open the lid, stir gently—the rice will be about three-fourths cooked. Simmer for 2 more minutes, then turn off the heat. Cover and let it rest undisturbed for 20 minutes to allow the rice to absorb the remaining moisture and fully cook.
Oven Method (OTG):
Preheat the oven to 200°C for 10 minutes. Once the biryani pot comes to a boil, cover the pot tightly with a lid and transfer to the oven. Bake for 20 minutes. Remove from the oven and let it rest, covered, for another 20 minutes before serving. This method ensures perfectly cooked rice without the risk of burning at the bottom.
After taking the pot out of the oven, do not disturb or open the pot for 20 minutes. Let it rest.
