No wonder Jawbusters take so long to eat -- it takes from 14 to 19 days to make a single Jaw Buster, The Original Jawbreaker. Jawbusters candy are created using the hot panned process. This process involves building candy pieces from single grains of sugar and tossing them into revolving pans while adding flavor, color and other candy ingredients. This process continues until the pieces become the desired size. Kosher Box
