Marinate the chicken with marinated sauce for 15-20 minutes.
Place the chicken on a baking pan, pour the remaining marinated sauce over the chicken and add 4 tbsp of oil to the pan to prevent the chicken from sticking. Bake for 20-25 minutes at 175°C until the chicken is lightly browned.
Fry the chicken that has been removed from the oven until cooked.
Saute the onions and garlic with 4 tbsp of butter until fragrant.
Add pepper, worcestershire sauce and sweet sauce. Stir well.
Add the fried chicken, stir well with the sauce, so the sauce soaks into the chicken. Turn off the heat when it's boiling and thickens slightly, make sure it tastes as desired.
Put on a plate, serve the butter fried chicken with lime and warm rice.
