Egg boiling techniques

I have always wondered how to make perfect boiled eggs. I came accross this useful information from just bento blog and it's worth sharing.

How to boil and prepare the eggs
Boil the eggs by putting them in cold water and bringing slowly up to a boil. Once the water is boiling, take off the heat, put on a lid and leave for 8 to 10 minutes.

It is pretty important to ensure that the egg yolk ends up in the middle of the egg, rather than leaning to one side. In order to achieve this you should roll the eggs around while the water is coming to a boil. (Note that this hands-on requirement is one reason why I rarely do this in practice for everyday bentos!)

To peel the eggs cleanly, dunk them in cold water, crack the shell over, and peel carefully. Very fresh eggs are hard to peel cleanly, but you rarely get very fresh eggs at regular supermarkets.
