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. Whisk until smooth and well blended.
03 - Add the chicken pieces to the marinade, turning and coating each piece thoroughly. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, ideally overnight for maximum 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 any remaining marinade, until the chicken is cooked through and lightly charred on the edges.
06 - Transfer the chicken to a serving platter, garnish with chopped fresh cilantro and lemon wedges, and serve immediately while hot.
