I have 2 1lb boxes of powerdered sugar sitting here in front of me
one lists ingredients as sugar,cornstarch C&H confectioners powdered sugar
the other lists ingredients as 97% sugar, 3% cornstarch (added to prevent caking) Imperial 10X confectioners powdered.
I use the one that tells me how much is in it, the 3% one...I have yet to find one that dosen't have cornstarch listed as an ingredient.
I know one beek that uses powered sugar, garlic powder and Coumaphos, all mixed togather in equal parts....thats scary...not gonna eat any of his honey
