To prevent jam from going moldy, housewives use sugar. The more you add, the longer the preparation will last.
There are other time-tested ways to protect jam from mold besides sugar.
Citric acid
For every kilogram of berry or fruit mass, you need to add one third of a teaspoon of citric acid.
Add the powder five minutes before it is ready. The jam not only does not mold, but it also does not crystallize.

Honey
