The science of food presentation

The science of food presentation

by Jozef Youssef Monday, June 22, 2015

In the first of our articles with the founder of collaborative gastronomic project, Kitchen Theory, we take a look at how the plating of food affects our experience of eating it.

More from this series:

Jozef Youssef founded the collaborative gastronomic project, Kitchen Theory, to explore the multi-sensory elements of eating.

At Kitchen Theory, we are continuously looking at the sensory attributes of the dining experience or what we call ‘neurogastronomy’. Research in this field looks at how all our senses (sight, smell, taste, hearing and touch) are involved in eating, dining and general food appreciation. It also explores the connections and interactions between the senses in relation to our understanding and associations with food. So what is it that makes us appreciate food? Is our enjoyment of food based solely on our sense of smell and taste? There is a little more to it than that . . .

As one of our academic collaborators, Professor Barry Smith, Founding Director of the Centre for the Study of the Senses, says ‘food has many dimensions . . . How it is presented, its aesthetics, how we enjoy it, how it works on us and how we grow it are all important elements which contribute to how we enjoy food.’

Over the past few years, many members of the press, as well as guests who attend our Kitchen Theory multi-sensory dining events, ask if any of the sensory aspects of our dinners can be used by the home chef. My answer is always, ‘Of course!’

As part of our mission to share knowledge in the field of neurogastronomy, we are very excited to work with Great British Chefs on a series of articles aimed at helping chefs (both amateur and professional) to understand the principles behind our sensory research and how to use them in their own cooking.

We begin with the sense of sight. The sentiment ‘we eat first with our eyes’ is widely held by many cultures around the world and one which I think we all intuitively understand. But is it true? And are there any key rules or principles for food presentation that the majority agree to be more appealing?

For the purpose of this article, we will look at three aspects in which we have conducted research: colour and taste associations, asymmetric plating verses central plating and, finally, the angle at which foods are presented.

Colour and taste association

The relationship between taste and colour.

A recent study* asked 452 participants from China, India, Malaysia and the US to view colour patches, shapes and textures online and to choose the taste term that best matched the image, then rate their confidence in their choice. The study found that the most notable taste and colour associations were: salty=white, sweet=red, sour=green and bitter=black.

When developing a dish entitled ‘The 4 Tastes’ for our Synaesthesia series of dinners, we put these findings to the test by developing four coloured, edible spheres, each representing one of the four most recognised and familiar tastes – sweet, sour, salty, bitter. As the dish is served, guests are asked to put the four elements in order of which they perceive to be salty, bitter, sour and sweet. Once the guest has followed the instructions, it’s time to put their perceptions to the test as they won’t find out whether they are right or wrong until they have tasted each element; for some this is a straight forward experience, for others (if their perceptions differ to the findings of the study) some of the elements may be incongruent and surprising. But what are our empirical findings? We found that the majority of our diners did, indeed, have the same associations as those revealed in the study.

Asymmetric vs central plating

Asymmetric plating has been all the rage for the last couple of years; it seems there are very few chefs out there who aren’t tempted to leave between half to three-quarters of their diners’ plates relatively empty. We can all probably think of examples where such dishes look good but do we actually find asymmetric dishes more appealing?

For our 2014 Nordic-inspired dining experience, Náttúra, we designed a dish entitled ‘A Taste of Nature’ and as with all our dishes we tried to find the method of plating the dish that guests would find most appealing. For this we turned to our regular collaborator, Professor Charles Spence, head of the Crossmodal Research Laboratory at Oxford University, and his team for a little help. We selected our two favourite plating options, one central and the other asymmetric, and put them to the test. Our research was based on over 600 respondents who rated both dishes based on how appealing they found the dish as well as other factors including how much they would pay for the dish. The results showed that respondents did indeed have a clear preference and it was towards central plating. Does this necessarily mean that the fashion for asymmetric plating is wrong? Well, not entirely; we believe there is still much work to be done in this area. Nonetheless, this does highlight the fact that how you plate your food does impact your guests’ perception and expectations of the dish.

Do angles matter?

Does a langoustine look more appealing when presented in the bowl at a 45 degree angle than when it’s at 90 degrees? This is what we are researching through our dish entitled ‘The Sight and Sound of Flavour’. However, other such studies have been conducted at the Crossmodal Research Lab, the most relevant of which is that by chef Charles Michel, whose study which reached 1667 participants looked at the importance of the orientation of food on a plate. The results clearly demonstrate that the majority had a shared preference for particular orientations (each black dot in the image represents the preference of a respondent so the denser the clusters of dots and the longer the line, the more popular that angle was).

Kitchen Theory at home

We have now seen that different colours are associated with specific tastes, that plating styles impact on perception of a dish and that the orientation of the elements on a plate matter to diners. So how do we put these findings to work in the kitchen? Here are some general plating tips based on our research into the ideas above and may others:

Contrasting colours are more appealing and make the food stand out.

The vibrant green is associated with freshness and better nutrition.
