Preserving sugar is a kind of sugar used for making marmalades, jams and preserves using fruits that are naturally high in pectin (such as plums, redcurrants, blackcurrants, gooseberries, greengages, damsons and Seville oranges). The large sugar crystals dissolve more slowly than those of standard granulated sugar and do not settle in the bottom of the pot or rise up as froth to the surface. This reduces the risk of burning and the consequent need for stirring. It also allows impurities to rise for easier skimming. Because it minimises scum, it helps to make jams (UK) / jellies (USA) clearer.
