The Master Marinade
In a large bowl, whisk together the Greek yogurt, ginger-garlic paste, lemon juice, Kashmiri chili powder, garam masala, ground cumin, mustard oil, and sea salt until smooth. Pat the chicken thigh pieces completely dry with paper towels, add them to the bowl, and massage the marinade thoroughly into the meat. Cover and refrigerate.
The lactic acid in yogurt and citric acid in lemon gently tenderize the dense thigh meat, while the fats in the oil dissolve the fat-soluble spices, driving flavor deep into the tissue.
A thick, uniform, rust-colored coating clinging tightly to the chicken without watery pooling.
