Season chicken with salt and pepper and leave aside for 3040 minutes.
Heat enough oil in a wok and fry seasoned chicken until lightly browned. Remove and set aside. Heat 1/2 cup oil in a saucepan and fry ground spices (A) for 56 minutes. Add spices (B) and (C) and continue to fry until fragrant and oil rises to the surface.
Put in chicken and fry until well combined. Bring to a simmering boil over low heat and cook until chicken is cooked and tender and gravy is fairly thick. Add seasoning to taste.
