Cut the chicken legs in to thighs and drumsticks (optional)
Heat a 30cm or 12" frying pan over a medium-high heat, and when it is hot, add the cooking oil. Sear the chicken on both sides for 2-3 minutes to get a nice colour, then transfer them to a plate.
Add the garlic and cook for 30-60 seconds, stirring constantly.
As soon as the garlic begins to go golden at the edges, pour in the soy sauce, vinegar and brown sugar mix and bring it to a boil.
Throw in the bay leaves and black pepper, and add the chicken thighs skin side down. Add a lid, reduce the heat to medium-low and cook for 10 minutes.
Remove the lid and chicken, stir in the coconut milk.
Return the chicken, skin side up this time and cook for a final 15 minutes.
