From a leg of lamb remove the top chunky meat that you can cook on the barbecue and keep the bone and the lower part of the meat which is usually more stringy.
1 shank of lamb
Stir-fry the diced onion, carrot and celery to make a soffritto
1 onion diced, 1 carrot diced, 1 celery stalk diced, 3 tablespoon olive oil
Once the vegetables are slightly cooked, add the meat and sear on all sides
Braise the meat until it is all brown, adding a sprig of rosemary and a half cup of red wine (optional)
½ cup red wine, 1 sprig fresh rosemary
Add the tomato sauce and the beef stock, stir and close the pressure pan
1 lb homemade tomato sauce, 1 brown beef stock cube
The lamb has to cook for only 35 minutes in the pressure cooker.
If you are using a normal pan, simmer it with a lid for 2 hrs
Place the lamb ragu in a serving dish and remove the meat from the bone. It will be very tender.
If you are serving the lamb ragu with pasta, add some sauce to it as soon as the pasta is ready and stir to season.
1 lb rigatoni pasta, 1 tablespoon salt
Serve the rest of the ragu on a serving plate and guests can top up more meat and sauce over the pasta
