It might put you off that this old recipe because it starts off “Place the barley in a large bowl. Cover with water; soak overnight”. But if you be bothered doing it the barley will make the soup delicious and when you add in the lamb and vegetables you’ll end up with a very hearty and warming winter dish.
As it says this is similar to a pastie, but instead of chopping the meat and vegetables up you layer them and then put a pastry lid on top. Although it doesn’t say to, I’d make sure you put a few slits in the pastry lid to let the steam out.
