In the United States, chocolate has a place in nearly every holiday celebration: heart-shaped boxes of chocolate for Valentine's Day, chocolate bunnies for Easter, wrapped candies for trick-or-treaters at Halloween, and cups of hot cocoa to warm Christmas carolers.
Sales of chocolate products in the United States total $13 billion a year.
The chocolate exhibition at Chicago's Field Museum opened on Valentine's Day and runs through December 31, then travels to museums throughout the United States until 2006.
Two books published in conjunction with the exhibit are Chocolate: The Nature of Indulgence, by Ruth Lopez, and Chocolate: Riches From the Rainforest, by Robert Burleigh (both published by Abrams).
