Grandmas Meat and Dumpling Casserole

This recipe is one I remember with great fondness. My grandmother would make up a big pot, with a cheap cut of lamb (that is the national meat of Wales!) , pile in loads of carrots, swede, turnip, mushroom, and then top the casserole with these dumplings. They would start off their life as golf ball sized blobs floating on the top of the casserole, and then 2 hours later, they would have expanded nearly double in size.
