Egg cutter
An egg piercer (also Eidorn , also colloquially Eierpikser ) is a kitchen tool, which in eggs , a small hole can be engraved into the shell to the air chamber to open to the outside. This enables pressure equalization during cooking , which is intended to prevent the egg shell from bursting. However, a study by the WDR science television magazine Quarks & Co was able to show that pecking eggs has no effect on whether an egg is damaged during cooking or not.
Construction
The construction of egg sticks prevents the needle from penetrating too deeply, which would damage the inner shell skin , and also prevents excessive stress on the sensitive shell . For this purpose, the pressure of the device is distributed over a larger area and the insertion of the needle is dampened by a spring or something similar.
In the original design from the 1970s, egg cutters consist of a small jar with a hollow and a hole in the middle of the lid and a needle in the middle of the base. Lid and base are connected to one another in a telescopic construction and are pushed apart by a spring. By placing the egg with the wider end and pressing it down gently, the shell is pierced.
In addition to being used as a stand-alone device, egg piercers are now also used as part of egg boilers or egg timers . There are also “designer models” on the market that differ considerably from the classic design, but fulfill the same function.
