    My frined boiled a bunch of brown eggs. She said they all looked fine except 1 - the egg WHITE was completely gray!! What is that all about?

    Never heard of that before.. I wonder if it was an older egg that got missed or something.. Very strange...

    That can happen with boiled eggs if they are boiled too long. I have never seen one go completely gray, but if you get a gray layer around the yolk, that is a sign of overcooking.

    if the white turns gray when boiled, maybe she had a small crack and Iron in her water.

    Never heard of the white turning grey. The yolk, yes. But not the white... [​IMG]

    It just happened to me. I've been boiling eggs for over 40 years and never had one before. It might be safe to eat but I won't chance it, besides it just looks gross [​IMG]

    Quote from internet search:

    people generally agree it is from cooking too long.
    "The egg yolk contains iron and the white (albumen) contains sulfur. During boiling the sulfur atoms are liberated and react with hydrogen ions in the white to form hydrogen sulfide (a gas). As gas forms, it diffuses in all directions and some reaches the surface of the yolk, where it encounters iron and reacts to form dark particles of ferrous sulfide.The egg yolk contains iron and the white (albumen) contains sulfur.
