Cover your cuts of lamb or mutton with cold water and add the onion, carrot, bayleaf and peppercorns.
To make the broth pressure cook for 30 minutes (or if you have a broth/soup button use that).
Strain the broth and discard the bones and vegetables. Chop the meat into small chunks and place into the strained broth.
Place in the fridge and allow the fat to solidify on the surface.
Once the broth is cold and there is a layer of white fat set on the top, use a slotted spoon to scoop the fat off.
Make sure to begin your soup in a clean bowl.
Add a little butter or oil and press the sauté button. Sauté the onion, garlic and herbs.
Return the lamb or mutton to the pot and coat it with all the flavour. Cancel the sauté function.
Add the tomatoes, broth, barley and vegetables.
Press the soup button or manually pressure cook for 30 minutes.
