01 - Make shallow diagonal slits across each piece of chicken to allow the marinade to penetrate deeply into the meat.
02 - In a large mixing bowl, combine the yogurt, lemon juice, tandoori masala, ginger paste, garlic paste, ground cumin, ground coriander, paprika, turmeric, chili powder, salt, and vegetable oil. Stir until a smooth, uniform paste forms.
03 - Add the scored chicken pieces to the marinade, turning and rubbing each piece to ensure complete, even coating. Cover the bowl tightly and refrigerate for a minimum of 4 hours, ideally overnight for maximum flavor development.
04 - Preheat the oven to 425°F (220°C) with the rack positioned in the upper third. Alternatively, prepare a hot grill for direct high-heat cooking.
05 - Arrange the marinated chicken on a wire rack set over a foil-lined baking sheet, or place directly on the grill grate. Roast for 30 to 35 minutes, turning once halfway through and basting with any remaining marinade, until the internal temperature reaches 165°F and the exterior is lightly charred.
06 - Transfer the cooked chicken to a warm platter. Garnish generously with chopped fresh cilantro and lemon wedges. Serve immediately alongside naan, steamed basmati rice, or cooling raita.
