Rock sugar
Rock sugar is large crystallized sugar used in syrups, braises and other preparations where its form affects dissolving.
About Rock sugar
Rock sugar is sugar formed into large, irregular crystals. It is used as a separate ingredient in East Asian cooking: Japanese ume plum syrup recipes layer it with plums, and Chinese braises use it to sweeten the cooking liquid. The large pieces dissolve more slowly than granulated sugar, which can matter to a recipe's method.
The crystals may be clear, white or pale gold. This entry means plain rock sugar, not brown slab sugar or flavoured rock candy. Although it is a form of sugar, replacing it with fine sugar can change how quickly sweetness enters a preparation; follow the recipe's specified form and quantity.
