If eggs have a green ring around their yolk, what does it mean?
The key to preventing the green ring is to avoid overcooking. For perfectly hard-boiled eggs, try the following method:
- Place eggs in a single layer in a pot and cover them with at least one inch of cold water.
- Bring the water to a full, rolling boil.
- Immediately turn off the heat, cover the pot, and let the eggs sit in the hot water for 12-15 minutes.
- Once the time is up, transfer the eggs to a bowl of ice water or run them under cold water to stop the cooking process.
This method ensures the eggs cook through without the excessive heat that causes the ferrous sulfide to form. The quick cooling also helps make the eggs easier to peel.
