When is an egg hard boiled?

An egg is considered hard-boiled when the white and yolk have completely solidified. This typically happens when the egg is boiled for around 10 minutes.

However, the exact time can vary slightly depending on factors like:

* Egg size: Larger eggs might require a bit more time.

* Water temperature: Boiling water will cook faster than simmering water.

* Altitude: Higher altitudes require longer cooking times.

You can test if an egg is hard-boiled by:

* Spinning it: A hard-boiled egg will spin smoothly.

* Peeling it: The shell should come off easily.

Here's a helpful tip: If you want a perfectly hard-boiled egg with a creamy yolk, try adding ice water to the pot after boiling to stop the cooking process.
