    I am not sure if this is the right category, but I have a question about an egg I peeled this morning. I was making hard boiled eggs and one of them had a greenish maybe grey tint to it. One end looked like it had air bubbles in the white part which now had the off color to it. It didn't smell bad, but I didn't take a chance cause I have never had this color egg before. The eggs were about 4 or 5 weeks old and around that time we had a really cold snap. I had a couple eggs freeze before I was able to bring them inside. A couple had cracked their shells. But, could this be the result of a once frozen egg?

    I have always thought the greenish/greyish tinge was a sign that the egg was overcooked. [​IMG]

    Is the tint in the white or yolk of the cooked egg? Do you add anything to your water while cooking such as salt, soda, vinegar (some do)?

    I put a little bit of salt in the water. The tint was through out the egg white. The yoke was yellow but not solid in the center. It looked like it had broken apart a little bit and was scattered through the egg white. All of the rest of the eggs were good. None had any tint to them and the all cooked for the same amount of time in the water.

    My theory would be that the shell and membrane was compromised and allowed water to get into the egg during the cook - and the white was exposed to something (likely iron) - is your water iron rich and/or what type of pan did you cook it in?

    The egg shell was intact and some of the others had burst and had some of the white come out, but the ones with the burst shell all were normal looking with no off color. Maybe just a bad egg. I just was curious what would happen to the egg if it was frozen when brought into the house and then thawed and cooked. I have to check the others that we collected around the same time an see what they look like inside.

    My water is not very high in iron. I cooked in a regular metal pot. And, there was only one egg out of the 6 that I hard boiled that looked like this.
