Why does a green ring appear around hard-boiled eggs?

Peeling the eggs becomes easier too when cooled quickly—another bonus.

For best results, use older eggs, which peel more easily than very fresh ones. And always store hard-boiled eggs in the fridge if not eaten right away.

A little attention to timing and cooling goes a long way. With these simple tweaks, you can enjoy perfect hard-boiled eggs—tender, flavorful, and free of green rings.
