Empty space
The most counter-intuitive and most effective principle. A full plate has no subject: the eye does not know where to settle. A plate left a third empty gives the food a point of attention.
Corollary: the larger the plate, the smaller the portion appears. The same quantity looks generous on a 24 cm plate and mean on a 32 cm one.
Odd numbers
Three quenelles read better than four. The eye spontaneously groups even numbers into pairs and looks for symmetry; an odd number forces it to travel the whole. It is an empirical rule of composition, not a law — but it works.
Height
One vertical element is enough to give relief: an upright leaf, a tuile set at an angle, one element leaning on another. Entirely flat, a plate photographs badly and reads badly.
But height must never prevent eating. A construction that collapses at the first spoonful is a design error, not a flourish.
The simplest test: photograph the plate on a phone. The camera flattens relief and removes raking light — it shows the composition as it is, without the help of the room.
Temperature
A cold plate under hot food cancels twenty minutes of cooking. An oven at fifty degrees, or very hot water, while you finish. It is the easiest professional habit to adopt at home, and the most neglected.
The colour of the surface
White falsifies no colour but contrasts poorly with pale food. A dark surface lifts greens and whites; an earthy one suits long-cooked dishes. our piece on food design sets out what the container does to the contents.
