Meticulously trim all fat and sinew from lamb racks. Separate lamb ribs by cutting between ribs with very sharp knife.
Place all marinade ingredients in pyrex or ceramic dish. Whisk well to combine ingredients.
Place individual lamb ribs in marinade. Turn to coat. Allow to marinate at room temperature for one hour or cover and place in fridge to marinate for four to six hours. Lamb and marinade ingredients can also be placed in a Ziploc bag. Turn individual ribs or Ziploc bag occasionally to distribute marinade evenly.
Heat barbecue to high or set cast iron grill pan over high heat. Remove from marinade and place lamb ribs on hot grill.
Grill approximately two minutes each side until grill marks have appeared and lamb is medium rare.
