Eggs will be easier to peel regardless of age if you drop them into boiling water water instead of cooking from cold. It causes the whites nearest to the shell to cook quickly and pull away from the shell.
If I recall correctly it’s because the proteins in the whites go through two phases as they cook. First they relax like spring partial uncoiling and then they either tighten back up and tangle with each other like, or they cross link with each other like a polymer (I forget which). Regardless of the exact mechanism, if you cook them fast enough, the proteins in the whites bind with each other before they have the chance to settle down and bond significantly with the shell lining.










I’m sure it works, but its it’s not the only way to to cook a perfect egg. And it is hilariously inefficient both in terms of energy spent to boil water for 32 minutes, and effort required to direct one’s focus primarily to boiling eggs for 32 minutes (plus prep time).
What is funny to me is that this process is just pulse width modulation which is exactly how electric stoves work. But instead of applying the duty cycle to the water to keep it at a steady sub-boil temperature, they applied it to directly to the egg to even out the temperature gradient inside the egg.
You achieve a very similar result by just doing a 2 minute flash boil to set the outer whites and then dropping the temperature with cold water or ice and just walking away while a sous vide stick controls an even temperature for the rest of the time. Now, I don’t have a sous vide stick, but I did get a variable temperature electric kettle for tea, so I have been using that for several years now.
What makes the periodic method consistent and ripe for virality is:
