Step 1

In a slow cooker, combine the vinegar, soy sauce, brown sugar, peppercorns, garlic and bay leaves and stir to combine. Add the chicken, turning to coat evenly. Cover and cook the chicken on low until tender, 2 to 2 1/2 hours.

Step 2

Remove the chicken from the slow cooker and place on a plate. Strain the cooking liquid into a small pot. Place over medium-high heat and simmer until reduced to a thick sauce. Place the chicken back in the slow cooker to stay warm while the sauce reduces.

Step 3

Spoon some rice into serving bowls. Top with the chicken and some of the sauce, then garnish with the pickled peppers and scallions.
