Cool Facts
Sugar does the work. Sugar is the main ingredient that keeps fruit preserves safe to eat for a long time. It stops harmful bacteria and mold from growing by pulling moisture away from them.
Sealed in glass. Fruit preserves are stored in glass jars that are sealed tight. This keeps air and germs out, so the preserves stay fresh and delicious for months or even years.
Sweet and tangy. Sometimes cooks add acid like lemon juice to fruit preserves. The acid makes them taste brighter and helps preserve the fruit even better.
More than just jam. While jelly and jam are the most famous preserves, people also make marmalades, conserves, and fruit butters. Each one is a different thickness and texture that works great on toast, in yogurt, or baked into pastries.
