What You Need to Know
The process relies on the acid-catalyzed hydrolysis of pectin, followed by heat-induced gelation that traps sugar molecules. The high sugar content lowers water activity, while the acidic environment activates pectin's gelling properties, resulting in a stable, viscous product that can be stored for months without refrigeration.
