Coffee is a good metaphor here too, because bad technique can ruin a good steak just as surely as good coffee. "knows how to use a meat thermometer and reverse sear" describes like 10% of the population or less, same with coffee - there are people who use a bad grinder and a not-regularly-cleaned Mr. Coffee with good beans and get gas station coffee, and there are people out there making solidly B+ class coffee using costco beans, a no name burr grinder, and a french press.
Edit for people who've never had good coffee:
"I don't like coffee. Can James Hoffmann change that?" https://www.youtube.com/watch?v=Z-iNAyu-ejo
Perhaps I'm crazy, but I truly can't taste much of a difference between "good" coffee and "bad" coffee.
I can certainly tell the difference between a good steak and a bad one.
I bet the same analogy can be applied to cooking a cucumber.
I know people who can cook a lot of food pretty well, but don't understand why they can't use a laser thermometer to check their meat.
Knowing really is half the battle.
