Input: [header] How to make powdered sugar [title] Choose a blender or spice grinder. [step] Keep in mind that sugar can scratch plastic or weak glass. A high-powered blender is the fastest and most effective option, but any blender or spice grinder can do the job. <sep> (A) The same old rule applies here: you can grind your sugar with the spice grinder but store it in a canning jar or tupperware with a lid. [substeps] If your sugar grinder doesn't come with one, consider using a hand blender instead. (B) [title] Pour 1/4 cup of powdered sugar into the blender or spice grinder. [step] If you are using a heavy handle blender, hold the handle firmly enough to not strain the sugar. (C) [substeps] Spice grinder or coffee grinders-which are essentially the same tool-pick up flavors from the ingredients they grind. Clean it thoroughly before using it for sugar. (D) [substeps] A hand-held blender, like the dairy counter blender, should be used for grinding sugar (or rice and cornstarch). [title] Mix together two cups water and sugar.
Output:
C
