When hard boiling eggs which are not very fresh the yolk can migrate to the outer edges. If you want to keep the yolk in the centre of the egg, buy very fresh eggs! I buy mine direct from the farm.
the yolk! yolk
Yolk is the yellow nucleus in the middle of the egg.
If you put eggs in boiling water, the heat will cook the eggs, causing the egg white and yolk to solidify. This process is commonly used to make hard-boiled eggs.
The yolk is the yellow part in the middle. The whites are the white, squishy part around the yolk. They are totally white in a hard-boiled egg. The shell is the thin, hard casing around the egg. Seriously, you should know this from kindergarten.
Hard boiling an egg involves a physical change. The heat causes the proteins in the egg white and yolk to denature and coagulate, resulting in a solid structure, but the chemical composition of the egg remains the same.
It goes to the center as the yolk is heavier.

The Yolk.
One can start by hard-boiling an egg and afterwards by only mashing the yolk in a bowl. Then there needs to be mixed some dry baby food, liquid baby food and a pinch of fish food flakes with the yolk. The paste obtained can be cooked to get sea monkey food.
If you are referring to the vitiline membrane which surrounds the yolk when the yolk is released into the oviduct it is only meant to keep the yolk intact.
The amount of fat in a food product is not changed by cooking as long as the food is not cooked in fat. So a hard egg yolk and a runny yolk both have the same amount of fat.
Very hard if left in boiling water (212F), however it more commonly refers to an egg slow cooked in water at anywhere from 145-160F to give a soft uniform consistency throughout the egg (yolk and white).More information:The asker may have misunderstood the description of the egg or misread the recipe. A 9-minute egg could be desired: both the white and yolk would be cooked through, but the yolk would be slightly softer than a hard-cooked egg.
