The Truth About Green Circles on Hard-Boiled Eggs That Nobody Told You

Extra Tips for Perfect Hard-Boiled Eggs

• Prevent cracks: Add a tablespoon of vinegar or a pinch of salt to the water. This can keep shells from cracking and leaking.

• Older eggs peel better: Very fresh eggs tend to stick to their shells after boiling. Eggs that are 7–10 days old usually peel more easily.

• Batch prep: Boil a dozen eggs at once and keep them in the fridge for quick snacks or salads during the week.
