This kitchen tip below comes from Lucile Bluford’s “No Apron Strings Attached,” published in the New Journal and Guide (Norfolk), September 16, 1933. Place the egg in a pan of water. If fresh, it will lie on its side. If a few days old, it will tilt upward. If stale, it will stand on end. If very old, it will float. A person who can judge an egg by how it sits in water does not eat or serve bad ones.
