When is flour sifted and measured for a recipe- do you sifted and then measure the amt called for or do you measure it then sift?

Yes, measure first, the dump it directly into the sifter and sift into (usually) a medium-to-large bowl where other ingredients will be/have been added.

I do not believe this answer is correct. I believe one cup "sifted flour" is sifted then measured. One cup of "flour, sifted" is measured then sifted.
