Rack of Lamb

The quality of meat depends very much upon the cattle from which it is sourced. This recipe calls for an Aurora rack of lamb, which many believe to be one of the finest suppliers of gourmet lamb cuts. The method of cooking employed here is known as sous-vide; to cook the lamb at low temperature for an extended period of time, thus ensuring succulent perfection in every bite. Palm oil is utilised for its delicate, almost neutral flavour, thus allowing for the infusement of the marinade without off-setting the herbacious aroma. Serve with fresh polenta and vegetables for nothing short of a magnificent dining experience.
