Next day saute Onion and Celery in butter until cooked. While it's cooking cut bread into small cubes.
Whisk eggs and add to bread cubes. Remove onion and celery from heat and add to mixture. Then mix in warm reserve cooking liquid from turkey giblets. Add enough to make it fairly soggy without turning the bread crumbs to mush. Add rest of ingredients to taste.
