Regarding what I explained earlier about adequately convey my thoughts, let me try here.
Carrots are one of those vegetables that are likely to be the least appealing items on a plate. Like cauliflower, Brussel sprouts and even green beans.
Who really likes carrots? I eat them but they would be one of my least favorite. If ordering in a restaurant and they are an option, do you choose them?
When I scrolled down to that pic, even on that plate, my eyes went straight to the carrots. If that dish had been sat down in front of me, My first bite is a carrot. Presentation is most important. The psychological aspect of cooking kicks in. If those carrots taste as good as they look, everything else is going to taste better than if you had tasted them first. And, those carrots will, taste as good as they look because your mind has already decided they will.
The black plate would kick all of that up another 2 or 3 notches. The best part is, all of this takes little to no more effort than what you/we normally do anyway.
Serviceware and Form mimicking are 2 of the 10 principles of cooking. There is a reason they are important. Use a piece of bark from a tree to serve roast duck on, or a painting to serve a bowl of salad. To stimulate your taste through smell, Aroma is another of the 10. Use cinnamon sticks as forks, or a banana leaf or oak leaf as a veil, so when you lift them they release the aroma.
Just throwing stuff out there to help make my point. As bad as I am trying to explain my thoughts, I'm a little better at it in person instead of here.
