01 - Make shallow slits across the chicken pieces 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 chicken pieces to the marinade, coating each piece thoroughly on all sides. Cover the bowl and refrigerate for at least 4 hours, ideally overnight for maximum flavor absorption.
04 - Preheat the oven to 425°F or prepare a hot grill for direct high-heat cooking.
05 - Arrange the marinated chicken on a wire rack set over a baking sheet, or place directly on the grill. Roast for 30 to 35 minutes, turning once halfway through and basting with any remaining marinade, until the chicken is fully cooked through and slightly charred on the edges.
06 - Transfer the chicken to a serving platter and garnish with freshly chopped cilantro and lemon wedges. Serve immediately while hot.
