The Master Marinade
In a large mixing bowl, thoroughly combine the chicken pieces with the Greek yogurt, ginger paste, garlic paste, half of the fried onions, chopped mint, chopped coriander, lemon juice, 2 tablespoons of ghee, Kashmiri chili powder, turmeric, garam masala, ground cumin, and 1.5 teaspoons of salt. Massage the mixture deeply into the meat. Cover and refrigerate for at least 2 hours, or overnight.
The acids in the yogurt and lemon juice break down tough muscle fibers, while the fats distribute the fat-soluble spice compounds deeply into the bone.
A thick, uniform paste coating the chicken cleanly with no excess liquid pooling at the bottom.
