A great recipe for rack of lamb on the grill. The blackberry preserves add a nice fruit flavor without being too overpowering. A fantastic year round treat.
Trim excess fat from the rack of lamb. Place into a glass baking dish or resealable plastic bag. Combine remaining ingredients and slather over meat portion of the rack. Cover with plastic wrap or seal bag and allow to marinate in the refrigerator for 8-12 hours.
Preheat grill for medium heat. Remove rack of lamb from baking dish (reserving marinade), wrap bones with aluminum foil and place onto the grill.
Cook lamb for 30-40 minutes, turning often and brushing with reserved marinade throughout the cooking process. Once the lamb has reached the desired doneness, remove from heat and let rest for 5 minutes before carving.
