If you are into chocolate research, responsible farming, and the health benefits of chocolate, you may want to check out Chocolate USA a website from the Chocolate Council of the National Confectioners Association. The website formerly was the home of the Chocolate Manufacturers Association. In 2008, the members of the Chocolate Manufacturers Association decided that the needs of its members were so closely aligned with those of the National Confectioners Association and the most efficient and effective method for future development would be to integrate the two organizations and to be known as the Chocolate Council of NCA.
The website is chocked full of information and provides links to chocolate resources and recipes. While I was looking around, I came across a pdf entitled "A Guide to Hosting a Chocolate Tasting Party". Well, that sure sounded fun. Follow the link to see the pamphlet. It contains a chocolate tasting how-to guide; a list of common chocolate descriptive terms; an overview of cocao %; and a chocolate glossary.
Even if you don't want to have a party, the pamphlet is very educational. Happy Tastings!
