Combine the chicken thighs with dark soy sauce, rice wine vinegar, and garlic in a mixing bowl. Cover and marinate for 30 minutes.
Warm the oil in a saute pan over medium heat. Remove a few chicken thighs at a time, careful to leave any garlic cloves behind, and add them to the pan. Sear them for 3 minutes. Flip and cook the other side for 3 minutes. Set the chicken aside and work in batches.
Once the chicken sears, return the thighs to the saute pan and top them with the leftover marinade.
Add light soy sauce, water, bay leaves, and black pepper. Bring the mixture to a boil over medium heat.
Lower the heat and simmer for 30-40 minutes until the liquid reduces by half.
Stir in the dark brown sugar and cook for another 5 minutes.
Garnish with thinly sliced scallions and serve with white rice.
Notes
Expert Tips:
Enhance the flavor and color of the chicken by marinating it for a minimum of 30 minutes. Doing so helps the chicken absorb the marinade and tenderize. The longer you marinate, the tastier the chicken will be.
Take your time browning the chicken. It will flavor the chicken and render the fat from the thighs, ensuring the sauce is thick and not greasy.
