Marinade the chicken wing with the soy sauces vinegar, sugar,ar salt, peppercorn, half the garlic, onion, ginger for 30-60 minutes- obviously the longer, the more flavourful. (If marinating for more than 20 minutes, put the chicken back in the fridge and only remove it from the fridge 20 minutes before you want to cook- you want the chicken to be at room temperature before cooking to make sure it doesn't dry out.)
In a pan, heat oil till almost smoking. Once the oil is hot enough, stir fry the remaining garlic, onions and ginger till fragrant (1-2 minutes.)
Add the chicken wings to the pan/ wok only- reserve the marinade and juices for later.
Pan fry both sides of the chicken till brown (about 3 minutes.)
Add the marinade and juices to the pan and bring to the boil. Add the bay leaves and water (add enough watertill the chicken is covered)- cover the pot/ wok and simmer for 10 minutes.
After 10 minutes, uncover the pot/ wok and add the potato and/ or carrots. Simmer 10-15 minutes till the chicken, potato and carrots are cooked and sauce is thick and sticky. Garnish then serve with rice and enjoy!
