01 - Make shallow slits across each chicken piece 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. Whisk until smooth and well blended.
03 - Add the scored chicken pieces to the marinade, turning and coating each piece thoroughly. Cover the bowl and refrigerate for at least 4 hours, or preferably overnight for the best flavor.
04 - Preheat the oven to 425°F or prepare a hot grill for direct 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 remaining marinade, until the chicken is cooked through and lightly charred on the edges.
06 - Transfer the cooked chicken to a serving platter, garnish with chopped fresh cilantro and lemon wedges, and serve immediately while hot.
