Mix jelly and mustard in saucepan and simmer on stovetop for 5 minutes to melt jelly. Remove lamb chops from rach and French cut, being careful not to remove the fat from the eye (the fat will protect the meat from burning on the grill). Allow sauce to cool completely. Submerge lamb chops in sauce and allow to marinade overnight (place in refrigerator). Grill over Hickory coals 4 to 5 minutes (for medium to medium-rare), basting with sauce as it cooks. Turn once half-way through cooking time. Prepare garnish sauce by browning shallots in butter and stirring in the white wine and rosemary. Serve lamb with garnish sauce and grilled potatoes and vegtables. NOTE: The marinade sauce also goes well with other foods including mushrooms.
