I've got another tip on boiling eggs. If you want centered yolks for deviled eggs, pickling, or plan on eating them whole and don't want wasted eggs due to the yolk being to close to the shell, all you have to do is stir them gently as they cook. Start with the eggs in room temp water and stir until they are to the soft boiled stage. This works really well if you are a fan of pickled quail eggs because the yolk is so much larger inside a quail egg compared to a chicken egg. I would loose lots of quail eggs to torn whites until I learned this little trick.
P.S. I also use Julia Childs method for prepping eggs for pealing and it is flawless.
