Substitutions
Granulated Sugar (blended)
Can be made by processing granulated sugar in a blender with cornstarch for texture, but lacks commercial fineness.
Superfine Sugar (Castor Sugar)
1:1Finer than granulated, dissolves faster, but not as powdery as icing sugar for smooth icings.
Erythritol (powdered)
Sugar-free alternative, zero calories, but can have a cooling sensation.
Cornstarch (for texture)
Only for thickening or preventing caking, not a substitute for sweetness.
Buying Guide
Look for brands specifying '10X' for the finest grind. Store in an airtight container to prevent caking.
