no they are same
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
Yes.
If you are measuring by weight, yes. If you are measuring by volume (i.e "cups"), not necessarily, since caster sugar has smaller grains and hence will "fit together" in the cup in a more compact way than granulated sugar will. This means that a cup of caster sugar will contain slightly more than a cup of granulated sugar will.
The main distinguishing feature of confectioners' sugar is that its a very fine powder (while regular sugar is often in powder form, it is more granular, hence the name granulated). This helps the confectioners' sugar dissolve faster, which may aid in some applications.
Caster sugar is finer and dissolves more easily than granulated sugar. Granulated sugar has larger crystals and is commonly used in baking and cooking, while caster sugar is often used in recipes where a smoother texture is desired, such as in meringues or custards.
Both work equally well for muffins. The only difference is that caster sugar is ground a little finer than granulated sugar. Granulated sugar might take a little longer to dissolve, but it will work equally well.
Powdered sugar contains more small particles than granulated sugar because it is finely ground and has a much smaller particle size. While granulated sugar consists of larger, coarser crystals, powdered sugar is essentially granulated sugar that has been processed into a fine powder, resulting in a higher number of smaller particles by volume. Consequently, if you compare equal volumes of both, powdered sugar will have a greater quantity of tiny sugar particles.
Granulated sugar has a higher surface area than sugar cubes due to its smaller grain size, which allows for quicker dissolution in hot liquid like coffee. The increased surface area means more of the sugar is in contact with the liquid, speeding up the dissolution process compared to the denser sugar cubes.
Cane sugar and granulated sugar are both types of sucrose, but cane sugar is derived from sugar cane while granulated sugar can come from various sources like sugar beets. In terms of taste, cane sugar is often considered to have a slightly richer flavor compared to granulated sugar. Texture-wise, cane sugar may have a slightly coarser texture than granulated sugar. Nutritionally, both sugars are similar in terms of calories and carbohydrate content, but some people believe that cane sugar may retain more nutrients due to less processing compared to granulated sugar.
Caster sugar has finer granules than regular (or "granulated") sugar. For cupcakes, you should be able to use regular sugar instead of castor without any detriment to the final product.
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.
No... Powdered sugar is icing sugar. Granulated sugar is white sugar that is in granules. Chemically they are identical. The difference is in the physical structure. You can create your own powdered sugar by using a blender and granulated sugar. It won't be as fine, but it will be closer.
