Um. . . I understand the chemistry perfectly, but I didn't know you weren't supposed to boil the eggs.
So, let me get this straight. You put the eggs in the pan with the water, turn the burner on, then cover the eggs and turn the burner off as soon as you get those big bubbles coming up, then you wait 15 minutes and the eggs are done? Are the yolks actually cooked? Man, and all these years I've been boiling the &%@# out of them for like 40 minutes or so. Oops!!!!

Ummmm ....That's the ticket! when you have a rolling boil i.e. big bubbles coming up in profusion, the likelihood of severely cracked egg shells with egg white oozing out and creating a mess plus the fact the shape of the cooked (boiled?) egg is now less than perfect after all that hard work of fertilizing, incubating, brooding feeding,watering,feeding,watering.feeding,watering...I'm not giving you any eggs!!!
What's even better is if one was to add some plain salt(none of that iodized or sea salt ridiculousness!) to the water...The boiling point will be lower than 212 F. Therefore, one can 'cook' the egg at a much lower temp lessening the probability of ring around the yolk. Also adding distilled white vinegar to the water will help to make the calcium in the shell harden so that when the whole egg is cooked then allowed to soak in ice water...the shell will slip right off with a minimum of cracking and the yolk will still be hot. Shelled eggs then can go directly into a brine to pickle or clean cold water to chill in the fridge. Don't use eggs with mayonnaise based salads until throughly chilled! All y'all take care now!
