Causes of a Grey Yolk
There are several reasons why the yolk of a hard boiled egg may turn grey. One of the most common reasons is overcooking. When an egg is boiled for too long, the iron in the yolk reacts with the sulfur in the white, which can cause the yolk to turn grey. Another reason for a grey yolk is if the egg is not fresh. As an egg ages, the yolk can become less vibrant and turn grey in color.
Prevention
There are several ways to prevent a grey yolk in a hard boiled egg. Firstly, it is important to not overcook the eggs. To avoid overcooking, it is recommended to cook the eggs for no longer than 12 minutes. Secondly, it is important to use fresh eggs when boiling them. Fresh eggs have a lower pH level, which can help prevent the yolk from turning grey. Lastly, it is recommended to cool the eggs quickly after boiling them. This can be done by running cold water over the eggs or placing them in an ice bath.
