This is a thread about why they use certain words, though. It isn’t a thread about how to cook an egg. They use the word “poached” to mean a certain consistency. To poach an egg means to produce an egg with that consistency. In fact, as far as the recipe is concerned, it doesn’t matter whether you heated up any water at all: if the instruction is “poach an egg” and you inject a Maxwell’s demon to heat up the individual molecules of the egg the appropriate amount, the result is a poached egg and that’s still what you call it.

They use words to mean what the result is.
