Caster sugar is a type of sugar that has been ground more finely than regular granulated sugar. It comes in both white (refined) and brown(unrefined) and gets its name from the container used to sift it over dishes. Learn more about caster sugar and why it is a preferred choice for baked goods to enhance the texture and consistency.
How Does Caster Sugar Differ From Other Sugars?
Caster sugar is different from other granulated sugars because it is superfine sugar that doesn’t contain any additives. It is ground very fine and dissolves more quickly than the large crystals of regular sugar.
Also, caster sugar maintains its texture without additives, unlike powdered sugar which often contains a bit of cornstarch to prevent clumping. Its ability to dissolve so quickly makes caster sugar a common ingredient in baking recipes and sweetening beverages.
Caster Sugar Nutritional Information
Caster sugar is high in calories and contains no nutrients. The finely granulated sugar is composed entirely of carbohydrates with no fat or protein.
Uses for Caster Sugar
- Sweetening beverages – dissolves quickly without leaving a gritty texture
- Meringues – fine grains create a smooth and stable structure
- Whipped cream – ensures a creamy consistency
- Cakes and cookies – blends perfectly into batters and doughs for a finer crumb and uniform sweetness
- Soufflés and custards – creates a smooth consistency
- Simple syrup – dissolves evenly in the liquid
Can You Substitute Caster Sugar?
Caster sugar has a unique consistency, but taste-wise, it is the same as any other type of sugar. You can replace caster sugar with any other type of sugar on a 1:1 weight ratio using a kitchen scale. Know that the final consistency of the dish may vary slightly.
How to Make Caster Sugar
If you don’t have any on hand, you can make caster sugar by blending granulated sugar with a food processor. Add cane sugar to your food processor and run it for about 30 seconds.
Note that when placed in a food processor, you will lose a bit of the sugar, so start with slightly more than your recipe calls for. The desired result is a finer consistency.
Caster Sugar Storage and Shelf Life
To prevent moisture and maintain quality, caster sugar should be stored in an airtight container in a cool, dry place away from any direct sunlight. If stored properly, caster sugar can last indefinitely, but it’s best used within two years.
Where to Find Caster Sugar
Caster sugar is located in the bakery aisle of most large grocery stores. It can also be ordered online from many retailers that sell baking supplies.
