Background Information:
Jawbreakers are made by slowly depositing layers onto a core (such as a single sugar grain or anise seed). Jawbreakers are made in large, rotating, heated pans. The candies take several weeks to manufacture, as the process of adding liquid sugar is repeated multiple times (more than 100 times over two weeks to make a one inch ball). Color and flavor are also added during the panning process. A 2004 episode of the Discovery Channel television program MythBusters episode subsection named Exploding Jawbreakers then demonstrated that heating a jawbreaker in a microwave oven can cause the different layers inside to heat at different rates, yielding an explosive spray of very hot candy when compressed; MythBusters crew members Adam Savage and Christine Chamberlain received light burns after a jawbreaker exploded
and finally... the process... how a jawbreaker is made... it is possibly the most fascinating candy process ever.
