So I was talking with my chef lately, about what makes cooking a joy, and what gives best result. of course best means different things for different folks, but after we both agreed, that the best way to cook piece of fish is to pan-fry it, he said, that maybe its best, but there are people who just dont know how to do it correctly. Thats how simple it is. You can go wrong pretty easily, it takes care and skill, but nothing combines crunch and mild flesh as good as frying pan.
I think it applies to basically everything else in cooking. How do you obtain dry meat? Why is risotto bland?
So for me its lack of understanding which causes cornercutting. Inventing new techniques which might not be better, but its easier to execute for someone who doesnt wish to master it, just does it.
