Grill pork chops over high heat for 1-2 minutes on each side, just until seared.
Place chops on a 24-inch (or longer) length of heavy-duty aluminum foil. Spoon preserves over chops. Wrap in foil, forming a packet.
Grill over medium-high heat another 10-15 minutes until chops are cooked through, to a minimum internal temperature of 145 degrees F measured with a meat thermometer.
