  • Since the OP never returned, I'm editing the title to match the body of the question, and adding in what I think was meant by the title.

Powdered sugar (as it is known in the US) is approximately 3% cornstarch by weight.

See, for example, United Sugar's website. This is typical of all manufactuers, however.

  • I tweaked the question slightly, if you want to add anything about how important it is to make it with exactly 3% cornstarch.
