Prepare the marinade: In a bowl, mix together all the marinade ingredients. Pour them over the lamb and let it marinate for 1 hour. Remove from the marinade and let stand until ready to cook.
While the lamb is marinating, prepare the vinaigrette. To make the vinaigrette, combine all the ingredients, except the oil, and blend. Slowly add peanut oil. Season with salt and pepper and strain, if necessary, into a bowl.
Season the lamb with salt and pepper and place it on a hot grill. Grill medium rare, about 15 to 20 minutes; or cut the rack into chops and saute them in a pan over high heat for about 2 minutes on each side. (Cook the chops in several batches, if necessary, but don't crowd the pan.)
Make an island of the sauce on each plate. Place lamb chops on center. Decorate with cilantro or mint sprigs on top and serve with stir-fried vegetable or stir-fried rice.
Consumption of raw or undercooked eggs, shellfish and meat may increase the risk of foodborne illness.
