In some contexts, the term powdered sugar is used to indicate all forms of refined sugar that have been ground or powdered. In other words, it encompasses any sugar with a fine grain including confectioners’ sugar. Confectioners’ sugar is a powdered sugar though not all powdered sugar is confectioners’ sugar.
In other cases, confectioners’ sugar may refer to a specific fineness, or the extent to which the sugar has been ground. The fineness of sugar is denoted by a number between 3 and 10 followed by an X. The higher the number, the finer the grind. Confectioners’ sugar is 10x sugar. Note that not all packages of sugar will have the fineness of the grind indicated on the label. Let’s review more of the similarities and differences between confectioners’ sugar and powdered sugar in another SPICEography Showdown.
