Icing sugar is a very fine type of sugar powder which is used to give texture and color to pastries and frostings. It is obtained by crushing the crystallized sugar until it forms a very fine powder, then adding corn starch or almond powder to give it a soft and smooth texture. Icing sugar is generally made from cane or sugar beet sugar, and is available in different colors, ranging from white to dark brown. White icing sugar is the most common and most similar to ordinary powdered sugar, while brown icing sugar has a slightly more sweet and more pronounced taste, thanks to its caramel flavor.
