I remember one of the first times I hard boiled an egg.
I removed the eggs from the refrigerator, put them in a pot, covered the eggs with water, sprinkled a little salt to prevent cracking, and waited for the pot to boil. Ten minutes later, I removed the eggs from the pot and put them in an ice-water bath. The famous test of a “done” egg seemed to indicate that this was sufficient for producing a proper hard-boiled egg.
Some of you noticed my rookie mistake and are chuckling.
