Start by crushing the garlic and preparing the chicken pieces. Pat the chicken dry for better browning. This step ensures strong flavor development later in cooking.
Heat oil in a large pot over medium heat. Brown the chicken on both sides until golden. This adds depth and improves the overall taste of the dish.
Pour in soy sauce, vinegar, water, garlic, bay leaves, and peppercorns. Avoid stirring immediately after adding vinegar. Let it simmer so the sharpness softens naturally.
Cover and cook on low heat until the chicken becomes tender. The sauce will reduce and thicken slightly. This slow cooking allows the flavors to blend beautifully.
