To achieve the best outcomes, I agree.
But even a cheap steak can be decent if it's cooked properly. And an expensive prime cut can be ruined by cooking it improperly.
Yes. It is about learning all of these things. Knowing what kind of cut you have, and how to treat it to best effect.
A very tough gristly cut can be improved by tenderizing. Going low-and-slow/sous vide to melt the connective tissue. Even grinding it up to make a hamburger steak / loco moco.
Once you know all of those things, choosing the right approach and executing it is not that hard. The steps themselves are simple.
It's this story all over again:
Any steak can be delicious with a butter bath and then hit it with that A1 :).
But the point is that no matter how well you cook the steak you're not creating quality, you're just getting the most out of what you have. The cow and the farmer created that quality. I believe we lose sight of that because so much of the value chain is not visible to us and we hyper fixate on the fun part, becoming a better barista/chef.
