The science of taste: Heston Blumenthal and Harold McGee

The Fat Duck did not emerge from the classical French kitchens or Michelin-starred institutions that shaped many of Europe’s most famous chefs.

Instead, its roots are found in libraries, science labs and the pages of Harold McGee’s On Food and Cooking. The relationship between Heston Blumenthal and Harold - part mentorship, part intellectual partnership - shaped not only The Fat Duck, but the modern discipline of culinary science itself. 

Their collaboration challenged tradition, dismantled long-held assumptions about cooking, and created an entirely new approach to flavour. 

This chapter explores that relationship: how it developed, how it transformed Heston’s thinking, and how their shared curiosity still defines the restaurant today. 

A Meeting of Minds 

Heston discovered Harold McGee’s work in the late 1980s, long before The Fat Duck opened its doors. Harold’s writing was revolutionary: instead of recipes, he explored the physics and chemistry of food - why onions make us cry, why eggs coagulate, what flavour actually is. 

For a young Heston - already obsessed with the multisensory experience of eating - Harold’s work was a revelation. 

Years later, as The Fat Duck was finding its footing in Bray, Heston reached out to him directly, beginning what would become one of the most influential intellectual partnerships in modern gastronomy. 

A Friendship Built on Curiosity 

The two men bonded instantly over a shared fascination with the mechanics of taste. 

Harold’s scientific clarity encouraged Heston to approach problems more methodically, using experimentation to challenge long-held assumptions.

At the same time, Heston’s interest in storytelling and sensory design illustrated to Harold how science could interact with emotion and imagination in a restaurant setting.

Breaking the Rules - Scientifically 

Together, Harold and Heston questioned some of the oldest “rules” of cooking: 

Searing meat “to seal in the juices” 
Harold’s research showed this was a myth - searing creates flavour through the Maillard reaction, not moisture retention. 

Stock must never boil 
Harold demonstrated that boiling does not “cloud” stock because of impurities, but because of suspended particles - which can be clarified later. 

Pasta requires large amounts of water 
A controlled experiment proved this unnecessary; it cooks perfectly well with minimal water. 

These discoveries were not mere academic exercises - they had direct consequences in the kitchen and expanded Heston’s creative freedom. 

The Birth of Multisensory Cooking 

While Harold provided scientific grounding, Heston translated those insights into dishes that combined precision with narrative and sensory play. This approach contributed to a new style of cooking that emerged internationally in the early 2000s.
