Rock sugar is a type of sugar that is formed into large, crystalline structures. It is made by crystallizing sugar syrup, which results in clear, large crystals that are often used in cooking and baking. Rock sugar is commonly found in various cuisines, especially in Chinese cuisine, where it is used to sweeten teas and desserts. Unlike regular granulated sugar, rock sugar has a milder sweetness and a unique texture. It dissolves slowly, making it ideal for slow-cooked dishes and beverages. Rock sugar is also sometimes used in traditional medicine for its perceived health benefits, such as soothing coughs and promoting digestion.
