What is jam sugar?

Jam sugar, also known as gelling sugar or preserving sugar, is a type of sugar specifically formulated for making jams, jellies, and preserves. It typically contains added pectin, a natural gelling agent found in fruits, to help the preserves set properly.

Jam sugar is often used in recipes that include fruits with low natural pectin content, such as strawberries, peaches, and cherries. The added pectin helps the fruit mixture thicken and set into a firm, spreadable consistency without the need for additional ingredients or lengthy cooking times.

When using jam sugar, it is important to follow the specific instructions on the package to achieve the desired consistency and set of the jam or jelly. Some jam sugar varieties may also include citric acid to help preserve the color and flavor of the fruit.

Overall, jam sugar is a convenient and reliable option for making homemade jams and preserves, providing a quick and easy way to achieve a perfect set every time.
