Gently heat the oil in a large heavy-bottomed frying pan. Add the garlic, spring onions, ginger, and spices and sauté for a couple of minutes without burning the ginger and garlic. Add the soy sauces, rice wine vinegar, sugar, and chicken stock and bring to the boil.
Carefully add the chicken thighs skin side down and add a little extra water, if necessary, until the thighs are just covered. Bring back to a gentle simmer and cook for thirty minutes. Carefully turn the thighs over and continue simmering for another ten minutes basting occasionally as the sauce reduces.
Lift out the thighs and keep warm. Strain the sauce then return to the heat and continue to reduce until thick and shiny.
