When chicken is done, remove it from the broth, de-bone and de-skin. Shred and return to the broth. Add a teaspoon of celery salt and more salt and pepper to taste. Bring broth back to a soft boil. Begin dropping tablespoonfuls of dumplings into the broth. Don't stir. Once all the dumplings are in the broth, let simmer for 10 minutes uncovered. I repeat, don't stir.
