Production

In general, jam is produced by taking mashed or chopped fruit or vegetable pulp and boiling it with sugar and water. The proportion of sugar and fruit varies according to the type of fruit and its ripeness, but a rough starting point is equal weights of each.

Packaging

The high sugar content makes jam keep for exceedingly long times before unsealing the packaging, and for a long time at room temperature after opening, as fruit preserves are typically of low water activity. Glass or plastic jars are often used to store jam that is not all to be used at once, as a replaceable tightly-fitting lid can be used.
