This is the answer humanity arrived at after J. Kenji Lopez-Alt cooked a shit-zillion boiled eggs and tried peeling them to see what actually worked. You can’t guarantee a 100% peelable egg 100% of the time, but this method gets you as close as we can with the technology he had. What’s more shocking (and disappointing to me) is how much bro science misinformation is getting posted about this. This isn’t exactly a hard claim to check.
