Preheat oven to 400 degrees. In a large Dutch oven or heavy pot with a tight-fitting lid, heat oil over high. Season chops with salt and pepper. In batches, cook chops until browned on both sides, 5 minutes per batch, flipping once. Layer chops in pot and add vinegar, 1 cup water, sugar, and garlic. Cover, transfer to oven, and braise until cooking liquid is reduced by three-quarters and chops are tender, 40 minutes. Sprinkle with parsley and serve with pan juices.
To store, let chops cool in braising liquid, then refrigerate overnight. Reheat gently to serve.
Try this with eight large chicken thighs instead of the pork chops.
