I used to buy superfine sugar and I don't know about you, but in my area, it is definitely not easy to find. I also find it more expensive than the common white granulated sugar. When I learned how to make superfine sugar, I never bought the store-bought ones again. These homemade ones will work just as well in recipes as store-bought superfine sugar - all with less hassle and more savings for your wallet too!
So, what is superfine sugar?
Superfine sugar, also known as caster sugar, is simply granulated sugar that has been ground into finer crystals. In some stores, they are sometimes labeled as quick-dissolved sugar or baker's sugar.
Is superfine sugar really necessary?
Superfine sugar is often used in the baking world as finer sugar crystals mean it would dissolve more easily into batters and cream easily with butter. This results in baked goods with a finer crumb and a lighter texture. That is why you would usually see this ingredient in recipes for delicate cakes, soufflés, and meringues. So if a recipe calls for superfine sugar, there is definitely a reason and substituting regular granulated sugar might not yield a very good result. It will be grainy or the texture will be off.
How do I make superfine sugar?
If your grocery does not carry superfine sugar, there is no need to worry as you can easily make this at home. You just need a food processor (or blender), dump the granulated white sugar and pulse (high speed) it until it's very fine. One to two minutes is usually enough to process the sugar. The exact time will depend on the amount of sugar you put and the power of your food processor. The key is to process until the sugar feels like a fine sand. You have superfine sugar when the granulated sugar is now in a very fine grain.
Is superfine sugar same as powdered sugar?
Superfine sugar is not the same as powdered or confectioners sugar. These two types of sugar are not interchangeable. Confectioners sugar has been pulverized to a powder that dissolves almost instantly in liquids and will not incorporate into a recipe the same way that superfine sugar will.
