cook eggs for how long?

Hiya ladies,
Just wondering how long do I need to leave my eggs in boiling water for now that I can't have runny ones? I hate trial and error so thought I'd find out the lazy way!

I leave mine for about 10mins :-k -
and dunk in cold water - so the yolks don't go grey around outside but are light yellow and fully cooked through.

when I went under 10 mins the yolk was still bright yellow though firm'ish but not completely solid -if that makes sense.

I've been out of home for hmm..4 years and every time I cooked eggs I had to call my mum, so last b'day she bought me an electric egg cooker! ;)
Makes the Worst buzzing sound but saves me a few phone calls!
I was always like, 5 mins? 10 mins? Now, do I start with cold water?
Call your mum(or someone similarly wise) is my advice :p

I have got one of those egg cookers too they are fantastic especially for hard boiled eggs so if you eat eggs alot I highly recomend getting one so so so easy you just add the cold water peirce the eggs and pop em in and turn on and when it is doen it buzzes and hey presto it gets the thumbs up from me :smt023
