I found online that 10x powdered sugar is more fine that 6x powdered sugar. If a recipe calls for sifted powdered sugar, do you have to sift if your using 10x. The recipe doesn't specify what grade use prior to it being sifted? Any help is appreciated....Thanks in advance.

I sift it all. Just because you'll eliminate lumps, and you never know what else might be in that box. Not trying to be gross, but quality inspectors don't catch everything

You should sift it. After sugar is milled, it sits around for a bit so it settles and sometimes form lumps.

So other than specialty or baking supply stores where can I get the 10X?

It is readily available at any supermarket. Domino's is 10X.

You can get it at Sam's Club in 7 lb bags for around $4.35 or so. It's Baker's & Chef's brand, and it's 10x sifted.

I just bought a 50 lb. bag for about $25 at Cash & Carry.

I use Domino's 10x powdered sugar and just recently stopped sifting it because I remember reading a post from Sugarshack that she doesn't sift PS anymore. I decided to try it to save time and it works great with no problems whatsoever!

I guess I just have never seen it on the bag that it is 10X.
Thanks!

I only sift if i have to buy it in the 1 lb boxes. The poly bags seem to keep moisture out better = less clumping.
