How many cups in a lb of confectioner sugar?
I checked the back of a 1 1lb box of confectioners sugar, and C
& H said there were 15 1/4 cup servings per box. Do the math
and that works out to 3 and 3/4 cups per pound. I also checked the
back of a box of the store brand, and the amount came out the same,
so it must be a fairly standard measurement.
