Wash and Soak the Basmati Rice for an hour atleast.
I used Chicken Legs and Thighs. Marinate the pieces with the Spices, Curd, Ginger Garlic Green chilies paste and Coriander Mint leaves. Keep marinated atleast for 30mins or overnight airtight.
Slice the Onions evenly. They dont have to be very thin or thick. I cut them lengthwise and then separate each and every strands for even cooking.
Fry the Onions in medium hot oil. Turn heat to high initially. Once color changes, turn the heat down stirring continuously.
Once the color gets golden brown drain them out on a tissue. Spread them out. I fried the onions in two batches as i used very less oil to fry. If you need the onions to be more crispy, then use lot of oil deep enough for onions to float.
Keep 1Tbsp of the Oil in which onions were fried and keep remaining in a separate container. The leftover oil can be used for your daily cooking imparts a nice flavor to any dish.
Add Ghee and fry the marinated chicken on high flame for first five minutes. Turn the heat to low and add sugar and 3/4th of the fried onions. If possible crush the onions first and then mix. Add salt to taste if required. Cover cook the chicken for 15 minutes on Low flame. Chicken should be 85-90% cooked only as it will get cooked further on Dum later.
Boil the Water with Whole spices, Lemon juice with the peel, Salt and Kewra Water. Once water gets boiled rapidly add the drained rice, mix and cook further on High flame for another 7-8mins till the rice is cooked atleast 85-90%. Remove the whole spices and the lemon peel.
Layer the Rice evenly over the Chicken in the Biryani pot. Add chopped Coriander Mint leaves. Leftover fried onions, Ghee, Saffron milk, food color and Kewra water.
Seal the pot airtight with an aluminium foil. Cover with a lid. You can also place a flat lid and then a heavy vessel on top for dum cooking.
Place the Biryani pot on a pan. Dum Cook on High heat for first 3-4mins and then on Low heat for 15minutes. Allow it to rest for another 20-30mins before serving.
Best served with Plain/Cucumber Raita. Bon Appétit!
