FRO, short for "Frosted," refers to a type of finish or coating that gives a surface a matte or semi-opaque appearance. This effect is commonly used in various materials, including glass, plastic, and metal, to enhance aesthetics and reduce glare. Frosted surfaces can also provide privacy while still allowing light to pass through. In the culinary world, "frosted" often describes desserts, particularly cakes and cookies, that are covered with a sweet icing or glaze. This icing can be made from ingredients like sugar, butter, and flavorings, adding both flavor and visual appeal to the treats. Popular examples include frosted cupcakes and frosted cookies.
