Ever peeled a hard-boiled egg and noticed a green or gray ring around the yolk? It may look strange, but it\u2019s completely harmless.<\/p>\n
The discoloration happens when eggs are overcooked. A chemical reaction occurs between sulfur in the egg white and iron in the yolk, creating a layer of iron sulfide. While safe to eat, it can make eggs look less appetizing.<\/p>\n
The good news? It\u2019s easy to avoid.<\/p>\n
For perfect hard-boiled eggs, place them in a pot and cover with cold water. Heat over medium heat until the water starts boiling, then turn off the heat immediately. Cover the pot and let the eggs sit in the hot water for 9\u201312 minutes depending on how firm you want the yolk.<\/p>\n
As soon as the time is up, transfer the eggs into ice water. This stops the cooking process instantly, prevents the green ring, and makes peeling much easier.<\/p>\n
A few extra tips:
\n\u2022 Slightly older eggs peel better than very fresh ones
\n\u2022 Adding a little salt or vinegar can help if shells crack
\n\u2022 Store boiled eggs in the fridge for up to a week in their shells<\/p>\n
