Step 1: Toast and Grind the Spices

In a dry pan over medium-low heat, toast the whole spices. Start with the larger spices like cinnamon and bay leaves, then add the smaller seeds. Toast for a few minutes until they become very fragrant and start to crackle. Immediately transfer the toasted spices to a mortar and pestle. Add freshly grated nutmeg and grind everything into a coarse powder. Set aside.

Step 2: Marinate the Chicken

In a large bowl, combine yogurt, ginger-garlic paste, Kashmiri chili powder, turmeric powder, 3 tablespoons of the freshly ground biryani spice mix, salt, and split green chilies. Mix until you have a smooth marinade. Add the bone-in chicken pieces and use your hands to coat each piece thoroughly. Cover the bowl and refrigerate to marinate for at least 2 hours, or preferably overnight for best results.

Step 3: Cook the Chicken

In a heavy-bottomed pot (like a biryani handi), melt 2 tablespoons of ghee over medium heat. Arrange the marinated chicken pieces in a single, even layer. Pour any leftover marinade from the bowl over the chicken. Cook for 30-45 minutes, allowing the chicken to cook through and the marinade to form a thick sauce at the bottom.

Step 4: Fry the Onions

While the chicken is cooking, prepare the fried onions. Thinly slice the onions, preferably with a mandoline. Place the sliced onions in a pan with cold oil. Turn the heat to low-medium and fry the onions slowly, stirring occasionally, until they are golden brown and crispy. Remove them with a slotted spoon and drain on a paper towel-lined tray. Reserve the flavorful oil.

Step 5: Par-Cook the Rice

Rinse the basmati rice several times until the water runs clear, then soak it in water for 30 minutes. Bring a large pot of water to a rolling boil. Season it generously with salt and a few whole spices (like bay leaf and cardamom). Drain the soaked rice and add it to the boiling water. Cook for 5-7 minutes until the rice is 75% cooked—it should be soft on the outside but still have a firm bite. Immediately drain the rice in a colander.

Step 6: Layer the Biryani

Once the chicken is cooked, begin layering. Sprinkle half of the fried onions over the chicken. Add a layer of fresh mint and cilantro leaves. Next, gently spread the par-cooked rice over the chicken in an even layer. In a small bowl, crush the saffron threads into the warm milk to create saffron milk, then drizzle it over the rice. Top with the remaining fried onions, a drizzle of the reserved onion-frying oil, the rest of the mint and cilantro, and a final sprinkle of the biryani spice mix.

Step 7: Seal the Pot (Dum Method)

Prepare a simple dough by mixing all-purpose flour with enough water to form a pliable dough. Roll it out into a flat disc large enough to cover the pot. Place this dough lid over the biryani pot and press the edges down firmly all around the rim to create an airtight seal. Brush the top of the dough with a little ghee.

Step 8: Bake the Biryani

Place the sealed pot on a baking sheet and transfer it to a preheated oven at 375°F (190°C). Bake for 25-30 minutes. The dough lid will puff up and turn golden brown, indicating the biryani is steaming inside.

Step 9: Serve and Enjoy

Carefully remove the hot pot from the oven. Use a knife to cut around the edge of the dough lid and lift it off. A large plume of fragrant steam will be released. Gently fluff the layers of rice with a fork or spoon to mix slightly. Serve the biryani hot, making sure to scoop from the bottom to get the chicken and masala. It can be served with a side of raita.

• Use bone-in chicken to keep it moist and prevent it from drying out during cooking.

• When toasting spices, rely on your sense of smell to know when they are ready; they should be very fragrant.

• Rinse the basmati rice multiple times until the water runs clear, then soak for 30 minutes to ensure long, fluffy grains.

• Start frying onions in cold oil to help them soften and cook more evenly for a crispier result.

• The dough lid (dum) is not for eating; its purpose is to create an airtight seal to steam the biryani perfectly.
