I Can’t Believe I Didn’t Know This About Boiled Eggs! | August 23, 2025

Annonce:

Have you ever peeled a hard-boiled egg only to discover a greenish ring around the yolk? While it may look odd, it’s a common and harmless occurrence. In this article, we’ll explore why this discoloration happens, how it affects your egg, and what you can do to prevent it.

🔬 Understanding the Science Behind the Green Ring

The green ring is the result of a chemical reaction between sulfur in the egg white and iron in the yolk. When eggs are overcooked, the heat causes these elements to combine into ferrous sulfide, which forms a greenish layer around the yolk. Although it might look unappealing, it’s completely safe to eat.

📊 Factors That Cause the Green Ring

Several conditions can increase the likelihood of this discoloration:

Overcooking the eggs

High cooking temperatures

Using older eggs, which have higher pH levels

⏲️ Cooking Time & Temperature Matter

The most common cause of the green ring is overcooking. To avoid this:

Bring eggs to a gentle boil in cold water.

Remove from heat and let them sit in hot water for 9–12 minutes.

Cool quickly in ice water to stop the cooking process.
