Why Do Hard-Boiled Eggs Turn Green?They look gross but taste fine |
When you hard-boil an egg, sometimes the yolk turns an unappetizing gray-green color. “The green-yolk phenomenon is actually very easy to explain,” says Kiasa Kuykendall, sales and marketing manager for Stiebrs Farms, an organic and free-range egg farm located in Washington state. “The longer you overcook it, [the more it] gets greener and turns gray.”
The discoloration is due to the formation of ferrous sulfide where the yolk and white meet, says Elisa Maloberti, the director of product marketing at the American Egg Board. It’s formed when “iron from the yolk reacts with hydrogen sulfide from the white.”
Discolored egg yolks are harmless, says Maloberti, but if you want to keep your yolks a more appetizing yellow, she offers the following guidelines:
• Keep the eggs in a single layer in the pan.
• Cover the eggs with water, bring the water to a boil over high heat, then turn off the flame.
• Let the eggs sit in the hot water for 15 minutes for large eggs (or 12 for medium, 18 for extralarge).
• Run cold water over the eggs after they’re done so they don’t overcook.
If you want green egg salad for St. Patty's Day, should you over cook the eggs on purpose? :)
"Why Do Hard-Boiled Eggs Turn Green?"
Fear of flying???
Or fear of frying?
I generally have better luck gently placing the eggs into already boiling water for 8-10 minutes. Never a hint of green.

Although I did not look at the YouTube video link above, I do know that putting your, just boiled eggs in ice water prevents the green sulfur ring surrounding the yolk. Thus make for beautiful yellow yolks.
My hard-boiled eggs used to have a little green line around the yolk until someone told me the proper way to boil them. I've never had the problem since......
Put cold eggs into salted cold water. Bring to a gentle boil. Turn off heat and cover pan. Leave in water exactly 10 minutes. This is a perfect hard-boiled egg and never green.
Hi group. I've recently turned onto the food stamp frenzie. I'm unemployed and have started "purchasing" eggs at my local deli in new york. I have typically fried eggs and dont choose to boil them for my kids. They like the yolks runny and prefer to dip their bread in them. The eggs from the deli that i've been frying have been turning green at the edges of the whites, not near the yolk. Is there something wrong with these eggs? There isnt much choice at the deli, they are the only grocer on the block that accepts food stamps, they dont have fresh veggies and dont regularly have milk or anything really fresh at all. I'd have to travel reel far for eggs or anything like that and i'm not sure other stores accept my credit. I just want to make sure i aint killin my boys with some sour eggs is all. Advice?
