In a small pan, combine the jam and vinegar. Over a low heat, cook until jam melts. Stir the mixture constantly.
Add the soy sauce, ginger, garlic, cayenne pepper. Remove from heat. Separate the glaze into 2 small containers, and set aside. (One will be to glaze the pork chops as they are cooking, and the other will be to put on your chops at the table).
Trim pork chops. Lightly brush chops with oil.
Place chops on a well-oiled grill.
Brush glaze on one side of chops, flip over chops, and cook 2-3 minutes.
Brush glaze on the other side, flip the chops over, and cook 2-3 more minutes on that side. (Throw the leftover glaze from this dish away).
Cut center to check for doneness. You want a light pink blush near the bone.
Add salt at the table.
Use remaining container of glaze on chops at the table.
