Egg timer

[citation needed] As technology progressed mechanical countdown timers were developed which had an adjustable dial and could be applied to a wide range of timed cooking tasks.

Most recently digital timers have also been manufactured and a wide selection of software is available to perform this task on a computer or mobile phone.

This kind of timer has the potential to more accurately indicate the state of the egg while it is being cooked as they do not rely on certain conditions (water hardness, hob temperature, atmospheric pressure).

This allows an observer to see the colour creep inwards through the disc and stop the boiling at the stage required.

[2] Other similar products use electronics to sense the water temperature and play a certain tune or series of beeps to indicate the state of the eggs.
