Mutton is meat obtained from sheep that are more than a year old and, in most cases, that weigh more than 100 pounds (45 kilograms). Mutton differs from lamb, which is the meat obtained from sheep less than a year old. Mutton is less tender and has a stronger flavor than lamb. In addition, mutton has a darker color than lamb. This color ranges from dark pink to deep red.
Mutton is a good source of protein, B vitamins, phosphorus, and iron. It is a popular food in Australia, the United Kingdom, and New Zealand. However, people in Canada and the United States eat little mutton, and it is seldom available in supermarkets.
