Hard-boiled eggs are boiled for longer than soft-boiled eggs, long enough for the yolk to solidify. They can be eaten warm or cold. Hard-boiled eggs are the basis for many dishes, such as egg salad, Cobb salad and Scotch eggs, and may be further prepared as deviled eggs.
Hard-boiled eggs are commonly sliced, particularly for use in sandwiches. For this purpose specialized egg slicers exist, to ease slicing and yield even slices.
There are several theories as to the proper technique of hard-boiling an egg. One method is to bring water to a boil and cook for eight to ten minutes. Another method is to bring the water to a boil, but then remove the pan from the heat and allow eggs to cook in the gradually cooling water. Others prescribe cooking in continually boiling water over heat for a shorter period of time.
Over-cooking eggs will typically result in a thin green iron(II) sulfide coating on the yolk. This reaction occurs more rapidly in older eggs as the whites are more alkaline. Immersing the egg in cold water after boiling is a common method of halting the cooking process to prevent this effect. It also causes a slight shrinking of the contents of the egg, easing the removal of the shell.
Hard-boiled eggs in their shells can be stored in the refrigerator for days to weeks.
