If you can boil water, then you can make a hard-boiled egg. But do you know how to make the perfect hard boiled egg? You might have heard some tricks and tips: bathe them in ice water, add a bit of acid or salt, or use your old eggs… Kenji’s here to teach us that none of that actually makes a difference. 

The only thing that makes a difference is whether you start them in hot water or cold water. If you drop them into cold water, the whites will stick to the shells, making them insanely difficult to peel. But if you drop them into water that’s already boiling, the shells will come off easily. 

Now, go crazy kids. 

For soft boiled eggs: Once your water has started to boil, lower them slowly into the pot, and leave them for 4-5 minutes. 

For medium boiled eggs: 7-8 minutes.

For hard boiled eggs: 10-12 minutes.
