If the bread you are getting is too crumbly for your tasts, I would
look at the grain size of the flour you are getting out of the
VitaMixer. Take a sample for your flour and store-bought flour and
compare them. Rub them between your fingers and see if one feels
'smoother' than the other.
I have been using a grain mill for years to grind my own grain. My
experiments have shown that a medium fine grain (the finest grain is
suitable for cakes...) is the best for bread. As you get into the
coarse settings, they are better suited to things like cookies. I
have made a recipe for Graham crackers over that last few years, and
it works out the best with a REAL coarse grind.
Hope this helps.
