Finally, a request. In this book I’ve sifted
through and synthesized a great deal of
information, and have tried hard to doublecheck both facts and my interpretations of
them. I’m greatly indebted to the many
scientists, historians, linguists, culinary
professionals, and food lovers on whose
learning I’ve been able to draw. I will also
appreciate the help of readers who notice
errorsthatI’vemadeandmissed,andwholet
me know so that I can correct them. My
thanksinadvance.
