What gives honeycomb candy its signature light, crunchy texture? In this episode of Chemists in the Kitchen, chemists Daisy Rosas, Kevin Aptowicz, and Joan Walker investigate the science behind this classic confection by making honeycomb candy with three different sweeteners: golden syrup, honey, and maple syrup. As they compare each batch, they explore how the molecular makeup of different sugars influences the candy’s texture, structure, and tendency to crystallize.

Along the way, the hosts explain the roles of sucrose, glucose, and fructose, demonstrate how baking soda creates the candy’s airy network of bubbles, and show why changing just one ingredient can dramatically alter the final product. Through this hands-on experiment, viewers see how chemists use controlled comparisons to answer scientific questions—and discover that even a simple candy recipe is full of fascinating chemistry.
