Cut the chicken into 1 to 1½ inch pieces, pat it dry, then combine it with the red chilli powder, garam masala, cumin powder, coriander powder, turmeric, salt, lemon juice, oil, ginger garlic paste, yogurt, and kasuri methi. Cover and refrigerate for 8 to 48 hours, or at least 3 hours, until the marinade looks thick and well attached to the chicken.
