Hard gummies are typically a result of low syrup usage. You can make a gummy without syrup and just sugar, however, the gummy will become very hard within a couple of days and if the syrup usage is low (below 20%). You might see these effects a couple of weeks after the production date. If the gummies are too firm right out of the molds, you can reduce the syrup usage to 25% as well as reduce the pectin usage until the desired firmness is achieved.
