Almost everyone says you should start soft or hard boiled eggs in cold water and then time them starting from when the water boils.
Now this, for me, is next to impossible. One thing is to watch your egg as it cooks when you crack it into a frying pan - fine - it;s a very short cooking and you might want to baste it or decide to flip it, or wet and cover it, and it requires some activity and is done in a minute
But waiting around for water to boil - now THAT is an activity that is so mindless and time consuming that i just can;t do it. I'm usually trying to do a dozen things at once, and then come back to the pot and find the water boiling away and don;t know how long it;s been.
So i always cook eggs lowering them carefully into boiling water and time them from there.
It's surprising how many cookbooks neglect to give the times with a boiling water start. Nowadays of course there is internet, but I wonder - if you boil them starting in cold water, do you actually stand around doing nothing, waiting for water to boil???
