Rock sugar, also known as crystallized sugar or rock candy, is a type of sugar that forms large, crystalline structures. It is typically made from sugar cane or sugar beet juice that has been processed and then crystallized into rock-like formations. These sugar crystals are larger and more transparent compared to regular granulated sugar, with a sparkling, glossy appearance.
The sugar crystals are often white or slightly off-white but can come in a variety of colors depending on the specific processing methods or added flavorings. Rock sugar is commonly used in cooking, particularly in Asian cuisines, for adding a mild sweetness to dishes without overpowering other flavors. It is also used in beverages, desserts, and teas, as it dissolves more slowly than regular sugar, making it ideal for long, slow infusions.
