The process of creating a sweet, often translucent coating for baked goods and confections involves dissolving sugar in a liquid. This mixture, when applied, sets to a smooth, glossy finish. A simple example includes combining powdered sugar with milk until a desired consistency is achieved, resulting in a coating suitable for donuts or cookies.
This technique offers several advantages, including enhancing the visual appeal of food products and adding a layer of sweetness. Furthermore, it can act as a protective barrier, preserving the moisture content of the underlying item. Historically, such coatings have been employed to both decorate and prolong the shelf life of various pastries and desserts.
