Once braised, these pork chops are browned once more so they have a crisp, caramelized exterior with a texture that you can pull apart with a fork.
Heat oven to 325 degrees. In a small bowl, combine salt, five-spice powder, coriander and black pepper. Put the pork chops in a large bowl, and sprinkle with the spice mixture, lightly coating the chops by patting and shaking them.
Place a large sauté pan over medium-high heat for 2 minutes. Add 1 tablespoon oil. Place pork chops in pan, and brown well on both sides. Pour off fat, then return pan to heat. Add wine, broth, orange zest, ginger and garlic. Bring to a boil, then cover pan and place in oven. Braise until tender, about 1 hour. Allow the chops to cool in the cooking liquid.
To serve, heat remaining 1 tablespoon oil in a large sauté pan. Add chops, and cook until reheated and browned, about 2 minutes a side. If desired, serve with polenta or risotto.
