Series Editor’s Preface

“It takes a tough guy to raise a tender chicken!” the late Frank Perdue

used to proclaim in his radio and t v advertisements. Physical chemist Hervé

This (pronounced teess), the internationally controversial molecular gastro-

nome, explains to us in understandable yet precise terms the science of ten-

derness.

What defines tenderness, anyway? How does one achieve it in the farmyard

and the kitchen? What chemical interactions give a chicken the potential to be

a gourmet chicken? How is tenderness perceived by the complex nerve end-

ings and taste buds of the mouth? The current cult of “Slow Food” may have a

basis in molecular science, or it may be mere Walden Pondish Romantic Rous-

seauism. After reading this absorbing book I now know what I mean when I

sing, “Try a little tenderness!”

Hervé This combines the seriousness of purpose and acumen of a respect-

ed scientist (Collège de France) with the aura of dynamic t v personality. He

succeeds more than others in making what seems recondite to some accessible

to all. We worry about making good French fries; here we read that there is

laboratory predictability in the choice of potato variety, the slicing technique,

and the discoloration that occurs when enzymes in the air hit the uncooked

spud. Each scientific food inquiry raised in this book takes root in specific

everyday (and useful) examples, the whys and wherefores of our very real culi-

nary dilemmas as home cooks and consumers.

| ix

Should one salt a steak before, during, or after cooking? We must under-

stand the chemical processes and consequences of that common ritual. How

does the shape of the wine glass affect the taste of a given wine? Science gives

us real answers. Our molecular gastronome could use equations, but instead

he uses words, readably, eloquently, and wittily.

How to cool down a drink that is too hot? Cool your almost-boiling morn-

ing Java with cold milk and it will take ten minutes, but wait for the coffee to

reach 75°f, then add the milk, and one obtains the same result after only four

minutes.

And your
espresso ristretto
(black)? One would think that the energy deflec-

tion of the metallic spoon and the diluting effect of sugar would be dramatic.

Blowing on the brew proves to be more efficient by half than stirring, even

though I had always thought that spreading the heat would lead to more rapid

cooling.

The era of culinology, a useful term immediately trademarked in our prof-

it-driven culinary culture by a group called Research Chefs of America, has

clearly arrived. How timely, then, is the publication of
Molecular Gastronomy
,

the liveliest addition to the growing bibliography exploring culinary science.

I might also cite the work of the Monell Chemical Senses Institute and the

books of such distinguished scholars as Peter Barham, Harold McGee, and

Robert L. Wolke.

Hervé This explores the chemistry, physics, and technology of produce cul-

tivation and selection, food preparation (cooking, freezing), tasting, and diges-

tion in his pioneering t v shows and acclaimed magazine articles. His labora-

tories at the Institutes for Advanced Research and the seminars he codirects

at the Collège de France have attracted many of the celebrity chefs to whose

kitchens people flock on pilgrimages of culinary initiation.

This book is as much about the science of eating and enjoying food as about

the science of its preparation. How does the brain perceive flavor and decide it

is good, and how do we detect textures? Is chewing healthful or even necessary

for gastronomic enjoyment? How does breaking down foods by mastication

alter their chemistry and release flavors? Study the effect and techniques of

flavoring and chewing gum, asserts our media-friendly gastronome, and you’ll

understand.

One of the most fascinating debates in current food science revolves around

the so-called fifth taste, umami. We had been taught that salty, sweet, sour, and

x | preface

bitter are the four taste sensations. As so often happens, new insights come

from Asia.
