I noticed at the bookstore that Joel Glenn Brenner’s book The Emperors of Chocolate is now out in paperback. It is a well written expose of the history behind Mars and Hershey. The revelations are startling. You learn how the companies are run, why American milk chocolate tastes sour (it really does!) and why M&M;’s are so addictive (they make them that way, of course!). There’s Mounds (pun intended) of enlightening facts about the candy industry, a few of which are listed here. Consider giving this book in lieu of chocolates to your favorite subversively-minded Valentine.
