Cornstarch-free powdered sugar
Is there anyone out there who knows of a source for cornstarch-free powdered or confectioner's sugar. I am looking for this to make French macarons. Some online sources say you can make your own by blending granulated sugar, but I doubt the sugar will be fine or consistent enough in texture to really work out well.
BTW, I don't want powdered sugar with wheat starch either - King Arthur has that.
Powdered sugar is just regular sugar ground to a powdered form with cornstarch added...you can make your own, minus the cornstarch
ok if it contains tapioca starch? if so, you can buy Miss Roben's on some of the sites that carry allergen-free foods. i think allergygrocer.com has it.
alternatively, as Cheryl said, you can make your own - you'll get the best results with a coffee grinder. once it's ground, add about 1 tsp of potato or tapioca starch per cup.
jono37, I made powdered sugar from granulated just to see if it would really work--and it did. But it was done in a food processor, not a blender.
Also, are you sure the granulated is cornstarch free?
one more option if you can use a product that contains tapioca starch - Trader Joe's Organic Powdered Sugar.
