Homemade Powdered Sugar?
Here it is, holiday baking season, and I am reminded once again just how much I dislike the powdered sugar sold at the supermarkets. It has cornstarch in it and I can taste it. I think I once heard or read about making powdered sugar at home using a food processor. Has any one out there done this successfully? If so, could you share the secrets of your success with the rest us? TIA
I just made a cookie recipe out of Cook's Illustrated Best Recipes, and in lieu of commerical powdered sugar, it called for regular sugar, pulsed for a minute in a food processor.
The end result appeared to be about the consistency of commerical powdered sugar without the starchy taste, but I had a hard time getting it off the sides of the bowl. Still, it seemed to work fine and the cookies were quite good.
I've put both regular and superfine sugar in a food processor (the miniprep) to try this. It took longer then a minute and the consistency was never there. Some was powdered, some was still grainy, just finer grains. Also, a little wisp of sugar smoke would waft up through the holes in the lid. At first I was wondering what was smoking but finally figured out it was just sugar.
I have read that putting sugar in a rock tumbler with ball bearings will do it.
