Lamb is sheep that is less than a year old. It is typically slaughtered when it is between four and 12 months old. The color of the meat ranges from pale pink to pale red and is generally lean. Its mild flavor also makes it versatile. lamb chops make an easy weeknight dinner, and a leg of lamb is a welcome change from the usual pork shoulder.
Mutton is sheep that is older than one; it is usually harvested at about three years old. The meat has a deep red color and is much fattier than lamb. The leg and shoulder are most commonly prepared, but the meat is tough, so it's often stewed to help tenderize it. Its flavor is strong and gamey.
