To mix dough: Stir bulgur (or cracked wheat) and boiling water in a large bowl. Stir together, 2 1/2 cups whole-wheat flour, 1 3/4 cups bread flour, salt and yeast in a large bowl. Stir the 1 3/4 cups ice water, honey and oil together, then mix into the bulgur. Stir the wet ingredients into the dry ingredients, scraping down the sides and mixing just until the dough is thoroughly blended. The dough should be moist and sticky, but stiff. If the mixture is too dry, stir in additional ice water to blend the ingredients, but don’t over moisten. If the dough is too wet, stir in bread flour to stiffen it slightly. Lightly coat the top with oil. Cover the bowl with plastic wrap.
