I've always assumed that graininess comes with using a better grade of
cheese... that the more expensive (dry) sharp cheddars would do that
because I've never had a problem with cheap cheddar. I don't even
bother making white sauce before hand. Once, I worked backward and
measured everything to figure it out and if the components added up to
a white sauce or not and they do - but I just use them without making
the sauce in advance.
