Grinding your own icing sugar

Also searched as: making icing sugar, powdered sugar, confectioners' sugar, icing sugar substitute

In short: Icing sugar is nothing more than finely ground granulated sugar. A powerful blender does it in a minute.

Picture it

Like pebbles ground into sand: it is the same stone, but it behaves completely differently.

You need · 5 minutes
  • 100 g granulated sugar
  • 1 tsp cornflour (optional)
  • high-powered blender or spice grinder
  • fine sieve

Fine sugar dust: only open the blender once it has settled.

Step by step: what happens

  1. 1
    Grind the sugar finely in short bursts

    The crystals break into tiny splinters. The surface becomes a thousand times larger.

    Surface area and cut size
  2. 2
    Wait two minutes before opening the lid

    The fine dust should settle.

  3. 3
    Push through a fine sieve

    Coarse leftovers would crunch in a glaze.

  4. 4
    Mix in starch if you like

    dust attracts moisture and clumps. Starch keeps it free-flowing.

    Sugar holds on to moisture

Result

About 100 g of icing sugar.

Keeps for

Keeps a long time, airtight and dry. Sieve out lumps before use.

What to use it for

  • Glazes and icing: it dissolves at once without crunching.
  • Whipped cream, shortcrust, dusting.
