Yes, you can. I use it instead of icing sugar (powdered sugar/confectioners sugar) because I think it tastes MUCH more delicous and less sweet and rich. But if you are going to use for whatever reason instead of icing sugar, I would recommend beating for much longer than you would with powdered sugar.
Though, please do not get confused with caster sugar and granulated. In America they use granulated sugar in baking, and I think (I may be wrong) they call caster sugar super fine sugar.
Also, you will get a better result if your caster sugar is newish. If not it can get gritty and become more-a-less like granulated. If so, put it into a sieve (sifter) and rub your fingers or spoon against it, this will get rid of chunks.
So, yes you can :D
Yes, you can use caster sugar to make buttercream icing. You will need to cream the butter and sugar until you get the correct texture.
The answer is yes, butter cream icing requires powdered sugar to come out correctly. If you don't have powdered sugar, regular granulated white sugar can be processed in an household blender,which will give it the right consistency for butter cream icing.
Icing sugar and caster sugar are not interchangeable. This is because icing sugar absorbs water whereas caster sugar does not. Switching icing sugar for caster in a baked good recipe will result in a good with a brick-like texture, whereas substituting caster sugar for icing will result in something liquidy and granular.
I would say a classic butter cream.
Yes, icing sugar is sweeter than caster sugar. This is primarily because icing sugar is finely ground and has a higher surface area, which enhances its sweetness perception. Additionally, icing sugar often contains a small amount of cornstarch to prevent clumping, but this does not significantly affect its sweetness compared to caster sugar.
i think its because caster sugar has smaller particles!!:)
No, its not, icing sugar is a fine powder whereas caster sugar is grainy crystals. Chemically they are probably the same, but the grain size is different. Caster sugar and granulated sugar are the same though I think.
You can thicken icing without using powdered sugar by adding cornstarch, cream cheese, or butter to achieve the desired consistency.
You can thicken icing without using powdered sugar by adding cornstarch, cream cheese, or butter. These ingredients can help make the icing thicker and more spreadable.
In some cases yes, but not if you're making icing. Icing sugar is far finer grained, and as such caster sugar will not be an adequate replacement in this case. (Your icing will be granular and not set properly). You may be able to if it's a meringue recipe, but you'd be better off finding a recipe that does not use icing sugar to begin with.
Either type of sugar is appropriate.
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.
