A Question of Temperature

Launch Tool

This activity shows how temperature plays an important role in melting and cooling chocolate. You can learn how fat groups in chocolate have different melting points. The tempering process stabilizes the cocoa butter (fat) crystals found in chocolate so that they become more uniform in size. The site includes step-by-step videos and recipes for chocolate, as well as articles about the history and origins of chocolate.
