Leg of Lamb Roast $22.00/lb$22. 00 Lb (leg typically weighs 4 to 6 pounds) Roast this roast, if roasting roasts are what you do. But, if you know your way around a smoker, we promise this will be as common as pork shoulder or dare we say brisket! That's a very bold claim but there's a buttery melty unmistakable taste and texture to lamb. Break out the fruit or "lite" woods here, be delicate as not to mask the natural "lambness" of this roast.
