DO-AHEAD TIP: Marinate lamb chops overnight or for at least 4 hours (see recipe).
In a food processor, combine first 6 ingredients (ghee through garlic powder); process until smooth.
Rub mixture evenly into lamb chops then place them in a large zipper-topped plastic bag; seal bag and refrigerate overnight or for at least 4 hours.
Preheat indoor or outdoor grill to MEDIUM-HIGH. Grill lamb chops for 3 to 5 minutes per side or until they reach desired level of doneness.
