Well, today I made cupcakes, and a reliable source told me (since we didn't have icing sugar at the time) to take normal sugar and grind it in our coffee grinder,… and then use it as icing sugar. At first, I thought it was crazy. Then I thought it was perfect! Then I didn't think it was so great. It was kinda hard to mix, and if you had leftover ground up coffee beans in there, the icing would end up with black specks in it..
In the end I used the same icing with much help from a very good friend. It wasn't as good as icing with icing sugar, but it was icing. My friend said it was too sweet for her, and I kind of agreed with her, since the sugar is actually sugar..
Be aware that after you apply the icing to your baked goods or food item, the icing hardens easily, but when poked the icing cracks. .
The icing may be too sweet for your liking .
It can easily harden .
It's kind of hard to apply .
When you use the sugar, it is the same as using icing sugar, use water or margarine for the icing. .
If the icing gets too hard, mix it up a bit and add some water. .
If the icing gets to liquidy, add a bit more ground-up sugar. .
Hope that helps!.
YOU CAN MAKE ICING SUGAR (CONFECTIONERS SUGAR) FROM GRANULATED OR CASTOR SUGAR..
Put granulated sugar in a blender and blend until it forms icing sugar. Icing sugar is just a much finer form of granulated sugar. Also, icing sugar is more expensive than granulated sugar so this is a way to save money too. In regard to the former (original) answer, some coffee grinders are a form of blender, just smaller. In fact, you can grind coffee beans in a blender. You can also grind peanuts in a blender to make peanut butter. ( Full Answer )
