Boiling eggs may seem easy, but overcooking can cause a green ring around the yolk. While harmless, it’s often unappetizing. The trick to perfect eggs lies in timing and cooling.
**⏱️ Boiling Time Guide**
Timing depends on how you want your yolk:
* *Soft (slightly runny)*: 6–7 minutes
* *Medium (jammy)*: 8–9 minutes
* *Hard (fully cooked)*: 10–12 minutes
Start with cold water, bring to a boil, then reduce heat or cover and let sit while timing.
**🟢 Why the Green Ring Appears**
The green-gray ring forms from a reaction between sulfur in the white and iron in the yolk. This happens when eggs are cooked too long or at high temperatures. It’s safe to eat but not visually appealing.
**❄️ How to Avoid It**
* Don’t overcook: stick to 10–12 minutes max.
* Cool eggs immediately in ice water.
* Use eggs that are about a week old — not too fresh or too old.
* Avoid rapid boiling to prevent uneven heat and cracking.
**🥚 Final Tip**
Rotate eggs gently in the first few minutes for centered yolks. With practice, you’ll have perfect, green-free boiled eggs every time.
