For best results it is recommended to use brined pork chops. Packaging will usually indicate that the pork chops contain a solution (usually 12%) to maintain moisture and tenderness.
If your pork chops aren’t pre-brined as described above, it is highly recommended to use a simple brine: A solution of ¼ cup (4 tablespoons) salt to 1 quart (4 cups) of water. Lay the pork chops (or other thin cut) in a single layer in a shallow dish and then pour the brine over top. Let this sit for anywhere from ½ hour to 2 hours before cooking. (thanks to reader Jack P.)
