Rack of lamb is simple to prepare and quite elegant for a proper dinner party. Racks have become so popular and expensive in the U.S. that chefs have turned to overseas sources to supply their restaurants at a much cheaper price. There are many New Zealand producers selling lamb with no added hormones or antibiotics. Small organic and free range producers in the U.S. sell their animals whole, so you not only get two racks you get everything else, legs, shoulders, shanks, etc. as well. Lambs are very small, 35 to 40 pounds, so if you split a whole one with a friend it is easy to use up all of the cuts. The herb marinade for the rack really perfumes the meat if it is done a day or two ahead of time. The same marinade can be used for many other cuts as well. It is best to remove as many of the herbs and garlic before roasting as they will burn and create off flavors.
