Step-by-Step Instructions

1. 1.Prepare Onions

   Slice both yellow and red onions thinly. Heat 2-3 tablespoons of ghee or oil in a large pot over medium-high heat. Add the sliced onions and fry until deeply caramelized and crispy, about 7-10 minutes. Remove from the pot and set aside, reserving the oil.

2. 2.Prepare Whole Spices

   In a dry pan, add cinnamon sticks, black peppercorns, coriander seeds, green cardamom, black cardamom, bay leaves, star anise, and fennel seeds. Toast over medium heat for about 1 minute until fragrant. Transfer the toasted spices to a grinder and grind into a coarse powder.

3. 3.Prepare Chicken and Marinade

   Cut the bone-in chicken thighs and drumsticks into desired pieces. Place the chicken in a large bowl. Peel and grate ginger and garlic, then crush them into a paste using a mortar and pestle. Add the ginger-garlic paste to the chicken. Add 1/2 cup full-fat yogurt, the freshly ground whole spices, 1 tsp turmeric powder, 1 tsp Kashmiri chili powder, 1 tsp ground cumin, 1 tsp ground coriander, 1 tsp garam masala, and salt to taste. Slice green chilies and add them to the bowl. Squeeze in 1 tbsp fresh lemon juice and add chopped cilantro and mint. Mix everything thoroughly with your hands (wearing gloves is recommended) until the chicken is well coated. Marinate for at least 30 minutes, or preferably longer in the refrigerator.

4. 4.Prepare Rice

   Pour 2 cups of basmati rice into a bowl. Rinse the rice under cold running water until the water runs clear, then drain. Bring a large pot of water to a rolling boil. Add 2-3 bay leaves, 4-5 cloves, 4-5 green cardamom pods, 1-2 black cardamom pods, 1 (1-inch) cinnamon stick, and 1 tsp black peppercorns to the boiling water. Add the rinsed basmati rice and cook for about 7-10 minutes, or until the rice is 70% cooked. It should still have a slight bite. Drain the rice immediately.

5. 5.Sear Chicken

   Heat 2 tablespoons of ghee or oil in a pan. Add the marinated chicken pieces and sear them on all sides until lightly browned, about 5 minutes per side. The chicken does not need to be fully cooked at this stage.

6. 6.Layer the Biryani

   In a heavy-bottomed pot (like a Dutch oven), spread a thin layer of the partially cooked basmati rice at the bottom. Arrange the seared chicken pieces over the rice. Top the chicken with a generous amount of the fried onions, a handful of cashews, some chopped cilantro, mint leaves, and a few lemon slices. Drizzle with 1 tablespoon of ghee. Add another layer of the remaining partially cooked rice. Top with more fried onions, cilantro, and mint.

7. 7.Prepare Saffron Milk and Dum Cook

   In a small measuring cup, add a pinch of saffron threads to 1/4 cup of warm milk and let it steep for a few minutes. Pour the saffron milk evenly over the top layer of rice in the pot. Cover the pot tightly with aluminum foil, then place the lid on top to create a tight seal. Place the biryani pot on a larger pan (or directly on a low flame) and cook on low heat for 25-30 minutes. This 'dum' cooking method allows the flavors to meld and the rice to finish cooking with the steam.

8. 8.Serve

   Once cooked, remove the pot from heat and let it rest for 10 minutes before opening. Gently fluff the biryani with a spoon, mixing the layers. Serve hot on a plate, garnished with additional fried onions, cilantro, and mint. Optionally, serve with a side of raita (yogurt sauce) and naan or pita bread.
