![]() ![]() ![]() This allows an observer to see the colour creep inwards through the disc and stop the boiling at the stage required. The plastic around the disc changes temperature relatively steadily and gradually from the outside to the inside of the plastic mimicking how an egg heats up while cooking. One such product is made of translucent plastic with a heat-sensitive coloured disc in the middle which changes colour at 80 ☌ (176 ☏). 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).Ĭlockwork mechanism of a mechanical egg timer New products have been developed which potentially allow for better egg timing these use the temperature of the water in which the eggs are being cooked to indicate the cooking state of the eggs. The task is simple to perform on most microwaves and oven timers. 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. 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. Traditionally egg timers were small hourglasses and the name has come to be synonymous with this form. Some modern designs can time more accurately by depending on water temperature rather than an absolute time. Early designs simply counted down for a specific period of time. Egg timer of the traditional hourglass typeĪn egg timer or kitchen timer is a device whose primary function is to assist in timing during cooking the name comes from the first timers initially being used for the timing of cooking eggs. ![]()
