Concerning the differences in flours, see the attached link for an
interesting article "How Different Flours Perform" from the San Francisco
Baking Institute on the topic. The only measurement of flour attributes
that I previously knew of was protein content...but there are apparently
many more measurements to be made (such as ash content, whatever that is).
There's even a lab in France that specializes in such measurements!
