No, this would not work. The amount of cornstarch needed to noticeably reduce the sugar's sweetness would result in a very unpleasant, odd-tasting product.
Frostings that are made without cornstarch and powdered sugar are thickened by cooking and beating. The beating incorporates air into the sugar syrup, producing a spreadable frosting.
In most things, No. Powdered sugar has cornstarch in it and has much less sweetening for the same amount.Clarification:Powdered (confectioners) sugar has only a minimal amount of cornstarch, which really doesn't affect the sweetness. The cornstarch is added to prevent the powdered sugar from lumping.But, as the answer above states, it usually cannot be used as a substitute for granulated sugar since it can result in the recipe not turning out as well.
sugar or just mix sugar with cornstarch
Powdered sugar contains cornstarch which could alter the texture of the canned goods. So powdered sugar would not be a good choice when canning.
i would not use granulated sugar while making buttercream icing. i would only use icing sugar. icing sugar usually has cornstarch mixed in with the powdered sugar. even if you added cornstarch to granulated sugar it would still give you a completely different texture than icing sugar...it would feel very gritty.
Powered sugar is pulverizing granulated sugar, with cornstarch added to prevent lumps.
Powdered Sugar
Mix half-and-half powdered sugar and cornstarch.
Synthetic sweeteners have the same consistency, but may alter the flavor of other items used in the recipe. Granular sugar can be substituted in most preparations. Knock on a neighbor's door.
Yes it does the powdered sugar does grow faster and the granulated sugar starts to mold
I wasn't aware that it did, but it would be there to keep it a powder. The cornstarch would coat the sugar crystals and keep them from sticking together.
Mix half-and-half powdered sugar and cornstarch.
