Have you ever run across a recipe calling for "superfine" sugar and been stumped? Superfine sugar, also known as caster sugar, is white sugar that has been ground to a very fine grain. Because of its small grains, superfine sugar dissolves more quickly than other types of sugar, so it is frequently used in cocktail recipes and in candy and pastry recipes where large grains of sugar are undesirable—for instance, in meringue or mousse recipes. But it can be hard to find in stores sometimes! Fortunately, it's easy to make your own superfine sugar at home.
What You Need
- Granulated sugar
- Food processor with metal blade
Time Required: 5 minutes
- Start with a little more granulated sugar than you will need for your final recipe. Some of the sugar will turn to dust, so it's better to make a little extra superfine sugar. Pour it into a food processor fitted with a metal blade.
- Cover the food processor with a kitchen towel—making superfine sugar produces sugar dust, and it can get the kitchen a little messy if you don't cover the processor.
- Turn the processor to high speed and process the sugar for about 1 to 2 minutes. The exact time will depend on the quantity of sugar and your processor. You want the granulated sugar to be much more powdery and in a very fine grain.
- After you process it, let the dust settle back into the processor for 10 to 20 seconds, then remove the lid. Your superfine sugar is now ready to be used! Store it as you would regular sugar.
