What causes the ferrous sulfide ring in a boiled egg? How can this be prevented?


The ferrous sulfide ring in boiled eggs happens when eggs are overcooked or heated at too high a temperature. The sulfur in the egg white combines with the iron in the yolk, the cooking water, or other iron sources. To prevent this from occurring, use fresh eggs, use stainless steel equipment, use low cooking temperatures, avoid overcooking, cool hard-cooked eggs quickly in cold water, and serve the eggs immediately.
