Sorry, never went back and finished the post last night.
Nanny would stew a whole chicken, very basic with just salt & pepper, onion and celery. Pull the meat off the bones after it cools, and remove the onions and celery from the broth. She made regular biscuit dough and pinched off pieces about the size of a ping pong ball. Drop them in one at a time to the simmering broth (after you've added the chicken back in), using a spoon to move them out of the way. Don't stir, it'll break up the dumplings. Once all of them are in, let it simmer a bit just until all the dumplings are cooked. Doesn't take real long.
