Eating with Our Eyes: The Power of Sight

Long before food hits our tongue, our eyes judge its appeal. The visuals tell our brain to prepare for deliciousness or give caution.

Why we say “that looks delicious!”

Even before getting a whiff of aroma, our eyes tell us so much about what we’re about to eat. Vibrant colours signal ripeness and freshness. Balanced composition on the plate suggests care in preparation. Elegant plating increases the perception of quality.

This visual information lights up our brain’s sensory and reward centres. We start salivating and our appetite revs up. Beautiful food just seems to promise it will taste amazing too.

Colours and shapes: The visual draw of food

Studies show red and yellow hues are particularly effective at firing up our appetite and desire to eat. These colours signify ripeness in fruits and vegetables. Circular, smooth shapes also entice us visually.

In contrast, blue tends to suppress appetite as it rarely occurs naturally in foods. Jagged shapes also register as less appetising. Utilising this food colour psychology, chefs meticulously engineer the visual appeal.

Nose First: The Deep Connection of Smell & Taste

Aroma is so tied to our perception of flavour that without it, food loses its sensorial magic. Let’s explore why scent is pivotal to tasty pairings and dining experiences.

Why a yummy smell makes our mouth water

Before we take a bite, odour molecules travel to olfactory receptors deep in our nose, priming our brain for what’s to come. Scent and taste work closely together, with smells amplifying or modifying flavours.

Think about holding your nose while eating chocolate or popcorn. The experience feels dull and flat without aromas like vanilla or butter enhancing the taste. Aroma is truly half our flavour experience.

Foods that smell and taste amazing together

Certain smell and taste combinations just make sensory sense to us. For example, smoky aromas enhance savoury umami flavours. Sweet scents like caramel exaggerate the taste of sugar. Citrusy aromas accentuate fruity notes.

Building these aromatic layers in dishes makes food and wine pairing more seamless. Understanding these classic matches allows chefs to engineer multi-sensory delights.

Hearing Our Food: The Role of Sound in Eating

The sounds of sizzling, crunching, and pouring contribute to satisfaction and enjoyment of meals. Let’s listen to why.

The satisfaction of a crunch or sizzle

Before diving into that perfectly crisp fried chicken or freshly tossed salad, our ears pick up sounds that prime our appetite and excitement.

Cracks and crunches signal freshness, while sizzles and bubbles convey preparation actions like frying, boiling, or simmering. These food sounds get our mouth watering and let us know texture is on point.

How sounds can make or break a food experience

The right sounds accentuate enjoyment of food. Too much noise easily wrecks the effect. While bacon crackling happily on the stove is appetising, loud smacking or slurping by others at the table is unpleasant.

Beverage sounds also contribute to refreshing sensations. The fizz of carbonation and gurgles of pouring signify thirst quenching. Work these sonic flourishes into home cooking for multi-sensory nostalgia.

Touch and Go: Feeling Our Food

Physical textures add fun dimensions that make dining more interactive and satisfying. Food scientists are still discovering the touch-taste connection.

The cool science behind why we love smooth, crispy, or bubbly

Nerve receptors and muscles in our hands, lips, tongue, teeth and throat respond to food textures. Crunchiness signals freshness. Creaminess conveys richness. Carbonation tickles playfully.

We prefer certain texture combinations instinctively because of how the mouthfeel components complement: Think crunchy nuts in creamy salad, effervescent soda with chewy pizza, crispy toast with runny eggs.

Temperature also taps into touch perceptions. Contrasts like hot soup and cold ice cream are extra appealing. Understanding these textures helps construct more enjoyable ingredient and dish pairings.

How texture plays with taste

Subtler interactions occur between feel and taste. For example, research found sourness decreases when thick, creamy textures coat the tongue versus watery foods. Smoothness appears to soften acidity.

How ingredients press against the tongue and palate alters how we perceive tastes. So chefs leverage textures not just for interest but also to influence the flavour experience itself.

Food Pairings: Sensory Combos that Rock

Certain pairings hit all the right notes, blending compatible aromas, sounds, textures, temperatures and colours for maximum sensory pleasure.

Iconic pairings that treat all our senses

Some combos strike the perfect chord by aligning our sensory experiences and expectations. A few that nail it on all fronts:

Coffee and doughnuts

Aroma – Roasted, caramelised smells
Sound – Gurgling coffee, doughnut crunch
Touch – Hot cup, fluffy doughnut
Sight – Steam swirling, glazed rings

Beer and pizza

Aroma – Yeasty, bread smells
Sound – Fizzy bubbles, cheese stretch
Touch – Cold glass, hot slices
Sight – Amber pour, colourful toppings

Wine and cheese

Aroma – Vinous fruity and nutty
Sound – Crackers crunching
Touch – Smooth cheese, glasses clinking
Sight – Colourful pairings

How chefs use sensory science for amazing dishes

By thoughtfully combining colours, textures, temperatures, sounds and aromas, chefs engineer dishes that engage all the senses:

  • Infusing aromatics like teas, herbs or smoke using sous vide or jars
  • Optimising crunch with crispy baked tuiles or fried sage
  • Building colourful layers and patterns with purees
  • Adjusting viscosities and temperatures for tableside pouring
  • Cooking proteins to perfect doneness for ideal slicing and plating sounds

This sensory design makes every bite multidimensional. Understanding the psychology and mechanics behind it allows home cooks to also build phenomenal full-sensory meals.

Brain Bites: How Our Brain Reacts to Sensory Foods

When all sensory aspects of food align, our brain lights up with pleasure and positive associations. Food memories also come flooding back.

The brain’s “yum” or “yuck” response

Eating first engages our basic survival senses to evaluate if foods seem safe and nutritious. If the senses all signal goodness, dopamine releases, kicking enjoyment into high gear.

But if anything seems “off” – smells or textures we associate with spoiled foods – our insula cortex activates to warn us away from possible toxins. These gut reactions happen in milliseconds, before we consciously think them through.

Why memories play a role in our favourite foods

Because scent pathways are closely tied to memory centres like the hippocampus, familiar food aromas instantly take us back. When our brain detects a well-loved smell, it expects a known pleasurable taste to follow.

Textures also tap into food memories. The creamy cold of ice cream, the crunch of a chip, pop of a soda – these sensations remind us viscerally of favourite treats and experiences growing up or special meals later in life.

Creating Multi-Sensory Meals at Home

Tips to make home-cooked meals a sensory treat

  • Marinate meats in aromatic rubs, herbs, teas or liquids
  • Coat crunchy roast nuts or toast with sweet or savoury spices
  • Use colourful ingredients like purple potatoes or patterned plates
  • Pour dressings, glazes, or sauces at the table
  • Bake breads or desserts so guests smell them cooking
  • Experiment with temperatures like chilled soups or frozen pops
  • Play themed music that matches cuisine styles

Fun experiments to try with family or friends

Get playful with sensory tests to appreciate how much smell, sound, touch and sight contribute:

  • Taste favourite foods with nose plugged vs open
  • Compare crunchy and soft cookies
  • Judge if cold or room temp dishes seem tastier
  • Switch up music and ambiance elements with meals
  • Adjust visual appeal of plates and see if it alters enjoyment
  • Review how beverage temps change the flavour
