Most supermarkets do offer boneless butterflied lamb leg for sale. It is usually already tied; you will have to remove the string and retie this recipe with your own string. Preparation for this cut has more steps than usual, but well worth it. The juices from leeks, garlic and herbs seep into the incisions and infuse the meat with a wonderful exotic flavour. Topped with pan gravy, your meal will have guests coming back for seconds. Serve with your favourite vegetables, potatoe or rice. The smooth taste of a Cabernet Shiraz or a crisp Chablis enhances the flavour of herbs in lamb. One of my favourite lamb recipes. Again, a supermarket handout recipe from the butcher shop provided by the promoters of New Zealand Spring Lamb.
