Of course you're going to follow orders, Blueicus. But the basic question is: Why did the chef tell you to sprinkle parsley in the first place?
My contention is he did so because it was fasionable at the time. And, furthermore, as soon as it goes out of fashion he will not only stop giving that order, he will explain, at length, why sprinkling parsley looks tacky and stupid and clutters the plate.
This concept of the fashionable culinarian applies to more than just garnishes. It permeates every facet of the industry. I notice, for instance, that celeraic is suddenly "in" with gourmet chefs. Nothing wrong with that. But how come these same people weren't using it two years ago?
I know somebody who captitalizes on this concept. He grows heirlooms for the trade, and, every year, pushes an offbeat vegetable to his restaurant customers. He knows that as soon as one upscale chef in his region puts it on the menu every chef around will do the same. And he's there to supply the market.
Understand, please, that I am not putting a value judgement on either the basic concept or on that farmer's marketing strategy. I'm just observing what goes on in the industry. It's neither right nor wrong, far as I'm concerned. It just is.
