Corned mutton is a canned meat delicacy. Mutton is the meat from an older sheep (lamb is from a sheep younger than 1 year old). It is fattier than lamb has a gamey taste to it and if you don’t like the flavor of lamb overall, this might be too intense of a taste for you. The canning process essentially starts by cooking the mutton first then placing in a brine to prevent spoilage. The salt in the brine is what makes any corned meat have a very salty taste. The pink color also comes from the corning salt/brine solution and maintains that pink colour even after being cooked, again. This whole process is the same for corned beef. Sometimes known in the West Indies as “bully beef” (bouilli, French for “boil”).
