sugar or just mix sugar with cornstarch
Powdered sugar is also called confectioner's sugar. In some regions it is also called icing sugar. Castor sugar is quite similar to powdered sugar and the two are sometimes used interchangeably.
Usually one pound of powdered sugar is in a box. Which is about 2 cups.
Powdered sugar contains cornstarch which could alter the texture of the canned goods. So powdered sugar would not be a good choice when canning.
yes it is the same
Just about 2 1/3 cups of granulated sugar = 4 cups of powdered sugar. Use the blender method.
Um, yes. Confectioners sugar is the same thing as powdered sugar - just a different name.
No, powdered sugar is best for the royal icing that goes on the cookie as decoration. For the actual cookie, use plain granulated sugar.
Yes
Yes, but only if the recipe calls for that TYPE of sugar.
Yes, better to use the powdered kind.
Powdered sugar, icing sugar and confectioners sugar are all the same thing. It is usually known as icing sugar in England and powdered sugar in the USA. Confectioners sugar is used as an international name.These are the same thing. Powdered sugar, icing sugar, and confectioners sugar are just different names for sugar than has been ground to a fine powder so that it dissolves very easily.
My recipe uses 6 oz icing sugar (powdered) and 3 oz of caster sugar and it works every time but I think the icing sugar (powdered) is important. Just checked 2 other recipes on www and they both use both types of sugar so I guess you should go and get some.
