How are egg timers made?
Also question is, how does an egg timer work?
To use an egg timer to boil eggs, drop the timer into a pot of boiling water along with the eggs and watch for it to change color. The edges of the egg timer will darken as the eggs cook, aligning with markings that indicate soft, medium and hard boil.
Moreover, why is it called an egg timer?
An 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. Early designs simply counted down for a specific period of time.
Place eggs in a large saucepan. Cover them with cool water by 1 inch. Cover the pan with a lid and bring water to a rolling boil over high heat; when the water has reached a boil, set the timer for the desired time. Boil for 6 – 7 minutes over medium-high heat for perfect hard boiled eggs.
