A really tasty and heartwarming dish.
Sear a leg of lamb or lamb shanks until browned. Place in a casserole dish.
Saute a chopped onion in butter until golden. Add chopped carrots and garlic. Add tomato paste and stir until the vegetables are coated. Pour in 2 cups of stock, a can of tomatoes, and a cup of red wine. Bring to the boil, then add everything to the casserole dish.
Place in the oven and cook for at least 2 hours. Longer if it's a big piece of meat. This dish can go long and slow for ages until the lamb falls off the bone.
Good with mashed potatoes.
