Pro Tips

Use an ice bath immediately after cooking to stop the process and peel easier.
Prick the large end of the egg with a pin to prevent cracking.
For the easiest peeling, use eggs that are 1-2 weeks old.

Fun Facts

"Water boils at a lower temperature at high altitudes, meaning eggs take longer."
"The 'green ring' in hard-boiled eggs is caused by overcooking, creating iron sulfide."
"Older eggs are easier to peel because the pH level increases over time."

Formula: Modified Charles Williams Equation (Protein Denaturation Math)
