Make the glaze. In a medium pot on medium high heat add the preserves, stock, vinegar, a nice pinch of salt and a few grinds of black pepper. Cook until the liquid reduces to a thin syrup, about 10-12 minutes.2.
Grill and serve. Heat grill or grill pan to high. Season the pork chops with salt and pepper on both sides. Place on the grill and cook until pork chop releases from the grill, about 3 minutes, then flip and cook on the other side, while brushing it with the glaze for another 3 minutes. If using a grill pan, be sure to do in batches so you don't steam the chops, but grill them and watch out for flare ups when you begin glazing!
