Step 1

Step 1.Whisk together the vinegar, soy sauce, sugar, pepper, ginger and half the chopped garlic. Place the chicken in a large bowl and pour over the vinegar mixture. Toss to coat. Cover and set aside in the fridge to marinate for 30 minutes.

Step 2

Step 2.Heat 1 tablespoon of the oil in a large, heavy-based pan over high heat. Remove chicken from the marinade and cook in batches (about 3-4 minutes each side) until golden brown. Reserve the marinade for later. Transfer the chicken to a plate and set aside.

Step 3

Step 3.Place the pan back on medium-high heat and add the remaining 1 tablespoon of oil. Add the onion and a pinch of salt. Cook, stirring for about 5 minutes or until the onions have coloured and are soft. Add the garlic and chilli and cook for another minute. Add the chicken pieces, reserved marinade, bay leaves and ¼ cup water. Cover, reduce heat to low and simmer for 30 minutes. Transfer chicken pieces to a large bowl or platter. Place sauce over medium-high heat and simmer for 15 minutes to thicken slightly. Pour sauce over chicken pieces and scatter over the spring onion.
