It can be a bit confusing with all the different sugars out there: icing, raw, muscovado, caster…the list is endless! Thankfully, it's easy to explain the difference between the two icing sugars on the market.

Icing sugar mixture, also known as confectioners' sugar or powdered sugar, is pulverised granulated sugar crushed together with a small amount (about three percent) of cornflour. This icing sugar is great to use when making icing for kids' birthday cakes or dusting sweet treats.

Similar in appearance to the former, pure icing sugar is also made from pulverised granulated sugar but contains no cornflour. For everyday cooking, icing sugar mixture does the trick; the only place where pure icing sugar is a must is when making royal icing, modelling fondant and the like.

If you are gluten intolerant, be sure to choose pure icing sugar over icing sugar mixture.
