I was shocked when I learned how to make powdered sugar. Also known as confectioners or icing sugar; I'll give you the easy steps below.
Clean pure sugar with no anti-caking agents...
1 cup granulated white sugar
blender (not a food processor)
Place the white sugar in the blender and process until it turns to
powder. That's it and this also equals one cup too (whatever amount
of sugar you need, just measure that amount in granulated sugar).
The commercial brand adds cornstarch, but I don't do that when I make
it. Frosting is so flavorful without the taste of cornstarch (yuck).
So there it is. Now, starting adding up how much money you are going to
save. Oh, one more thing...Your going to get sick when you see this.
EXTRA-FINE SUGAR
1 cup granulated white sugar = 1 cup extra fine sugar
blender (not a food processor)
Place the white sugar in the blender and pulse two or three times until
the granules are extra-fine and smaller in shape. That's all there is
to this too.
