I do not intend to start a discussion about which came first, the chicken or the egg. I leave that to others :-)
However, this post is about boiling eggs, and how to always achieve the same quality of a process.
I had a summer job at “Sjømennenes Helsehjem” many years ago, and how to boil the eggs was a hot topic. The customers / residents were not always pleased with the boiled eggs. However, it was complicated to please them since some residents were very happy while others were dissatisfied, with eggs cooked exactly the same way.
They had different preference for quality.
