Jawbreaker: The History, Ingredients, and Craft of a Classic Hard Candy

Background

Jawbreakers are hard, spherical confections that are so dense they often require sucking rather than biting. Ranging from the size of a hazelnut to a golf ball, they come in a wide spectrum of flavors and colors. Though originally a trade name, the term has become generic for any candy of this type and remains popular among children, especially in vending machines.

Historical Context

Egyptians were already crafting sweets with honey, fruits, spices, and nuts, long before sugar was known. The first recorded use of sugar dates to A.D. 500 in India, and it reached Europe around A.D. 1100 through the Arab world. Initially a rare spice used mainly medicinally, sugar became more accessible by the 16th century, enabling the first industrial candy production in Europe.

Candy hardness correlates with the temperature to which sugar is heated: low temperatures yield chewy candy, medium temperatures produce soft candy, and high temperatures result in fully crystallized hard candy. The jawbreaker falls into the hard candy category, akin to many mid‑19th‑century American penny candies. By the 1800s, the U.S. hosted nearly 400 candy factories producing a wide array of confections.

Development of the Jawbreaker

The iconic jawbreaker was popularized by the Ferrara Pan Candy Company of Forest Park, Illinois. While the term “jawbreaker” first appeared in English in 1839 as a word meaning “hard to pronounce,” it later became slang for a dentist. Ferrara Pan, founded in 1919 by Italian immigrant Salvatore Ferrara, produced the first commercial jawbreakers using the hot‑pan technique. The company remains the world’s leading producer of hot‑pan candies.

Ingredients

The core ingredient is sugar; all other components constitute a minor fraction. Manufacturers add natural or artificial flavors, a palette of artificial colors, calcium stearate as a binding agent, and carnauba wax for a glossy finish.

The Manufacturing Process

Hot‑Pan Production

Jawbreakers are crafted using large copper kettles—circular pans with a wide mouth—that rotate over a gas flame, keeping the sugar tumbling. The confectioner, known as a panner, begins by pouring hot liquid sugar along the pan’s edge. Each grain of sugar eventually crystallizes into a candy, growing as surrounding grains form a spherical lattice. Over 14–19 days, the panner adds liquid sugar over 100 times, ensuring even, perfectly round candies.

Flavoring and Coloring

When the candies approach their final size, the panner introduces pre‑measured flavoring and coloring. Added at the pan’s edge, the rotating motion distributes the ingredients uniformly across all jawbreakers.

Polishing

After about two weeks, the finished candies are transferred to a polishing pan—identical to the hot pan—where they rotate with food‑grade wax. This process coats each candy, giving it a smooth, shiny surface before packaging.

Measuring

Jawbreakers are first measured into small assortments by a dedicated machine. The candies roll down a tilted ramp into a central chute, then into trays arranged on spiral arms. Each tray holds a specified weight (e.g., one pound); once full, the tray is released into the bagging system.

Bagging

A high‑speed bagging machine uses a single layer of thin plastic to form, fill, and seal bags. Heated jaws melt the plastic along seams, creating sealed containers that are automatically dropped onto a conveyor for final packaging.

Quality Control

Quality checks are primarily visual. Workers periodically sample jawbreakers, inspecting the crystalline structure for concentric rings and conducting taste tests. The process’s simplicity means elaborate chemical analyses are unnecessary.

Byproducts and Waste

Defective jawbreakers cannot be re‑melted due to their fully crystallized sugar; they are ground down or discarded, resulting in minimal waste. The overall process produces no significant byproducts.
