One of my favourite aha moments: Back when I was much younger virtually every cookbook said you should add olive oil to pasta cooking water. I could never figure out why. Later people pretty much poo-pooed the practice saying that it was some old wives tale about stopping the pot from boiling over or some such thing. Fast forward many years and I was trying to work on a bolognese sauce. My wife likes meat/tomato sauc…
A better way is to cook pasta in a pan, adding water bit by bit as you would in a risotto (look up "pasta risottata"). In Italy no professional chef I know would allow oil in the boiling pan ("that's what Frenchies do, because they don't know how to cook pasta without making it stick" being the common answer)
If the result is the same, I'm all for that method.
