You’re probably correct that there are other methods for perfect eggs, but I believe that is a bit reductive. Boiling first then reducing the temperature, while similar, is definitely not the same as periodic temperature change, aside from it adding the same total energy to the system. But the rate that energy is added is the critical variable.

Don’t get me wrong, your method is good, but I don’t think the method in the paper only has the advantages you list. The periodic temperature change is important, and they detail precisely why that is.

Having said all that, I’m certainly not doing this. I’m all about easy and don’t need eggs to be a certain way. I just thought it was neat.
