On the home page to CC, I see there is a recipe for gumpaste by clomo. In the recipe it calls for "pure icing sugar". Is that the same as confectioners sugar???
Can anyone help??
In her post she states the recipe comes from a very old book so in today's language, yes it would be confectioner's sugar (aka: powdered sugar).
If the recipe came from someplace like England then it would mean confectioner's sugar that did not contain any cornstarch. I don't know of any brands here in the states that does not add cornstarch to prevent caking/clumping.
I live in Canada and all of our icing sugar has some cornstarch in it. I was recently in NY and bought some Dominos 10X at a grocery store to try. I don't really see any difference.
With gumpaste you use cornstarch when rolling it so I doubt it would make any difference.
