Sprinkle ground saffron over ice cubes in a small bowl and let it melt at room temperature.
In a small bowl, mix the cumin, coriander, paprika, turmeric, and cinnamon. Divide the spice mix in half: one portion for the chicken and the other for the rice.
Mix one-half of the mandi spice mix with 2 tablespoons of olive oil, 1 teaspoon kosher salt, and half of the bloomed saffron to create a paste.
Rub this mixture generously allover the 2 chicken halves, ensuring it's well-coated. Cover and let the chicken marinate for at least 30 minutes (overnight for deeper flavor).
Preheat the oven to 400°F. Place the marinated chicken in a 9x13 baking dish and cover it with aluminum foil. Roast for 45 minutes, then uncover and roast for another 45 minutes until the chicken is fully cooked and the skin is crispy and golden.
While the chicken is roasting, heat 2 tablespoons of olive oil in a large pot over medium-high heat. Sauté the onion until golden.
Add the remaining mandi spice mix, cardamom pods, salt, and pierced dried limes.
Stir in rinsed basmati rice, bay leaf, the remaining bloomed saffron, and water.
Bring to a simmer, then cover and cook on medium low heat for 25 minutes, until the water is absorbed and the rice is tender.
Turn the heat off and let it sit for 10 to 15 minutes before fluffing with a fork.
