Grilled Orange-Chili Pork Chops: one for the end of summer

This recipe for marinaded sweet-spicy pork is one of my favorites for outdoor grilling season, which is quickly drawing to a close here in Seattle. The sweetness of orange marmalade is a nice counterpoint to spicy chili powder, mustard, pepper, and garlic. I think of this as a sort of quick-fix gourmet BBQ. I am sure BBQ purists would object to my use of the term, since I use a high-quality cut of meat here (top loin pork chops) instead of the more typical tough BBQ meats that must be cooked a long time to achieve tenderness. This marinade caramelizes beautifully, creating a delicious sweet-spicy-smoky flavor. It could be used to great effect for "real" BBQ meats if desired, but the cook time must be adjusted accordingly for different cuts of meat.
