Unity

Basically, there is unity when the plate looks like one meal that happens to be made up of several items rather than like several unrelated items that just happen to be on the same plate.

Create a center of attention and relate everything to it. In a main course, the meat or fish is generally the center of attention and is traditionally placed front and center. Other items are placed around and behind it so as to balance it and keep the customer’s eyes centered rather than pulled off the edge of the plate.
