To Jack Allen -
It's not possible to make CRUSTY anything in a bread machine. The
crust on bread is formed by a combination of high temperature and an
infusion of steam at the beginning of the bake. To do this, use your
bread machine (if you must) to knead the dough and then bake the loaf
in an oven, preferably on a pre-heated baking stone (which will
absorb the heat) and under which a heavy (as in cast iron) pan has
been placed. When you place the dough onto the baking stone, pour
boiling water (wear a LONG oven mitt) into the heavy pan and quickly
close the oven door. Better yet, place clean rocks inside the heavy
pan while the oven is preheating.
Good luck!
