A hard boiled egg is made of..... egg. It is simply a whole egg, in the shell that has been placed in boiling water. The heat causes the liquid egg inside the shell to become solid. The yolk of the egg becomes the yellow center, and the clear "white" of the egg becomes the white outer part of the boiled egg. Remove shell, add salt to taste, eat.
