  6. Why Green?? • This is caused by overcooking the egg. The green color is a result of overheating causing the iron and sulfur compounds in the egg to express. You can prevent it by gently boiling the egg, and plunging it into an ice bath when it is done. This stops the carry-over heat from continuing to cook the egg

  7. Temperature and Egg Cookery • The Temperature Timeline of Boiling an Egg • Egg yolks, on the other hand, follow a different set of temperatures: • At 145 degrees: They begin to thicken and set up. • At 158 degrees: They become totally firm, but are still bright orange and shiny.

  8. At 170 degrees: They become pale yellow and start to turn crumbly. • 170 degrees-plus: They dry out and turn chalky. The sulfur in the whites rapidly reacts with the iron in the yolks, creating ferrous sulfide, and tinging the yolks.
