Why Do Egg Yolks Turn Green

Even if eggs aren’t the main ingredient, we often end up adding them throughout the cooking process of stuffing, minced meat, batter, dough, soup, pate. It seems that there isn’t a product as useful as this one, and it is true. Just two eggs a day can improve your well-being and prevent the development of numerous health problems. But why do egg yolks turn green, and is it okay to eat those?

If you’ve ever encountered this problem and are wondering whether or not hard-boiled green yolks are harmful to you, we have the answer.

Why Do Hard-Boiled Egg Yolks Turn Green?

Ordinarily, when egg yolks turn green, it signifies that you’ve overcooked the eggs. Such a blue-gray, greenish tint appears due to a chemical reaction during cooking: the yellow color turns dark green due to the formation of iron sulfide at the junction of the white and yolk. The longer you cook the egg, the stronger the reaction.

If you are unsure how long to boil eggs to avoid this discoloration and achieve the perfect yolk consistency, read on. To begin with, opt for the freshest eggs for cooking. Yes, they can be harder to shell, but in 90 % of cases, they do not change color.

How to Cook Perfect Hard-Boiled Eggs Every Time

If you plan to boil multiple eggs at once, use a pan that comfortably fits all of them on the bottom. Fill the pan with cold water, making sure that the liquid covers the eggs by only an inch.

Wait for the water to boil and then remove the eggs from the stove. Leave covered for 10–12 minutes. If you are going to these eggs in a salad or any other cold appetizer, cover them with cold water immediately after cooking.

I am an English major with a love of languages and fiction, and with an incurable travel bug. In my free time, I read fantasy, drink copious amounts of coffee, and like to go see movies. Culinary art means everything to me. My main hypostasis is the taster, though. The music school has taught me to appreciate the symphony of airy meringues, to create harmonious overtures of light snacks, hard rock of meat, fish, and vegetables on the grill. Choir classes have accustomed me to hear and feel the people nearby and create perfect harmonies of sounds.
