Superfine sugar- or Bartender's sugar, is more course than powdered sugar. Superfine sugar is similar to castor sugar (and can substitute each other), but if I were to put it in order, Superfine would have the largest granules, and powdered sugar would have the smallest. Powdered sugar cannot be substituted with superfine sugar, or castor sugar, since it's too fine :3.
Yes It has been procesed in the same way!
No - superfine sugar probably means caster sugar, which is basically the same as normal, white granulated sugar but milled into finer grains. Confectioner's sugar is also called icing sugar or powdered sugar and has been milled right down to a fine powder.The answer is - they aren't directly substitutable - you might be able to do it in some recipes, but it will depend on what you're making.
Yes, you can use granulated sugar as a substitute for castor (caster) sugar in a cake. Caster sugar is a quick dissolving sugar. So it will be necessary to grind standard granulated sugar in a food processor before using as a replacement. A blender can also be used.
Yes because superfine sugar is regular granulated sugar it's just been ground into finer crystals so it can be dissolved easier in many light recipes where you would not want the grainy texture of regular sugar, like in merinques and angel food cake. You can use superfine sugar in any recipe and be successful, it's when you try to substitute regular granulated sugar when it calls for superfine that you run into trouble because it will be too grainy or possibly lumpy. You could always make your own version of superfine sugar by putting regular granulated sugar into a food processor and chopping it up for a minute or two and it would be simliar to store bought superfine sugar.
granulated sugar means less fine sugar. fine sugar is the same as castor sugar!
Caster sugar's closest American equivalent is superfine granulated sugar, which can be hard to find; it is also known as bar sugar, as it is used to mix cocktails. It is sold in 1 pound boxes under the Domino brand. You can make it by running regular granulated sugar for several seconds in the food processor with the metal blade; this grinds the sugar to a finer consistency (superfine).
Caster sugar is called "superfine" sugar in the United States. Do not confuse with confectioner's (powdered) sugar to which cornstarch has been added.
For those not familiar with caster sugar, it is called extra fine sugar in the US. Golden caster sugar is naturally refined caster sugar so it has a slightly golden hue because of a bit of molasses due to processing. It is not the same as brown sugar. Brown sugar is white sugar mixed with molasses but it is far stickier because extra molasses has been added. If you can't find golden caster sugar you might try taking turbinado sugar and running it through the food processor.
No, caster sugar is fine-ground granulated sugar. Confectioner's sugar is a mix of ultra-fine sugar and a starch; it is sometimes called icing sugar.
castor sugar is white sugar that has been ground fine, but not as fine as confectioners sugar. It can be made by putting white sugar in a food processor for a few pulses
Powdered sugar has a buffering agent in it that keeps it fluffy and prevents lumps. This means that powdered sugar has a finer texture but doesn't work well in clear drinks, as they won't remain clear, even when the sugar dissolves. Superfine sugar is pure sugar, intended to dissolve easily. It does however have a slightly crunchier texture. So, if you don't mind the texture change, you can substitute superfine when the recipe calls for powedered sugar, but not the other way around.
