Cover eggs with cold water, ensuring they’re submerged by at least one inch.
Bring water to a rolling boil over medium-high heat.
Once boiling, turn off heat, cover the pan, and let eggs sit for 10-12 minutes.
Transfer eggs immediately into ice-cold water (an ice bath) for at least 5 minutes to halt the cooking process.

Serving and Storage Tips: Peel and serve your eggs fresh with a sprinkle of salt, pepper, or paprika. Store unpeeled boiled eggs in the refrigerator for up to one week in a covered container. For best results, peel eggs just before serving.

Variants:

Soft-Boiled Eggs: Shorten the resting period to 5-6 minutes for soft, runny yolks.
Flavored Eggs: Marinate peeled eggs in soy sauce, vinegar, or pickling brine for extra flavor.

Are green yolks safe to eat? Yes, they’re perfectly safe, though slightly less appealing visually.
How can I prevent green yolks? Avoid overcooking by timing the eggs correctly and using an ice bath immediately after cooking.
