A good product is clear and firm enough to hold its shape when turned out of the container, yet quivers when moved. Preserves are spreads containing small, whole fruit or uniform-size pieces in a clear, slightly gelled syrup. The fruit should be tender and plump. Conserves are jam-like products that may be made from a mixture of fruits. They may also contain nuts, raisins, or coconut.
Marmalades are soft fruit jellies containing small pieces of fruit or peel.
They often contain citrus fruit. Fruit butters are sweet spreads made by cooking fruit pulp with sugar to a thick consistency. Spices are often added. Butters are not gelled. For successful jams, jellies, and other fruit products, a proper ratio of fruit, pectin, acid, and sugar is needed.
