My way to make HB Eggs is to put eggs in cold water and bring to a rolling boil, cover, turn off the heat, let sit for 20 to 25 min.
Run cold water over them, drain the pot and fill with ICE. run some more cold water in it.
let them sit untill the ice melts.
They will usually peel very easy.
Of course there is always that ONE egg !
I think that the Ice condenses all the leftover water into steam on the inside of the egg, and forces the shell away from the egg.
All I know is a high school "lunch lady" told me this one, and it works for me.
