Mutton and lamb cuts
Because mutton and lamb come from the same animal, they are both available as the same cuts of meat. As you might expect, a cut of lamb will be smaller than the same cut of mutton, and there are some other key differences too. Mutton is fattier and more flavourful than lamb, but it is also tougher, and will require more cooking, particularly if the meat is taken from a hard working part of the animal like the leg or shoulder.
Where the animal was farmed may also have an impact on flavour and texture. Sheep that are farmed in the USA are typically grain-fed, contain a higher proportion of fat and have a milder flavour. Sheep from Australia and New Zealand, on the other hand, tend to be leaner, grass fed animals, with a stronger flavour.
Shoulder
The shoulder is a flavourful cut, but because shoulder muscles are worked hard while the animal is alive, it can also be tough. Lamb and mutton shoulder should be cooked low and slow, so stewing, slow-roasting and braising are all great ways to prepare this cut. For extra flavour, leave the bone in while you cook it.
Lamb and mutton shoulder is usually sold whole or halved on the bone, but is also available boned and rolled for roasting, diced for casseroles, curries and stewing, or minced for making into meatballs, moussaka and shepherd’s pie.
