Combine water, yeast and 2 cups of the flour in a mixing bowl. Set aside to sponge for 15-20 minutes, until risen and bubbly (warmer weather takes 15 min, cooler temps usually needs 20).Add honey, oil, salt, (gluten, if using), and 4 cups of flour. Mix until dough starts to clean sides of bowl. Change to dough hook (or turn out to knead by hand), and knead 6 to 7 minutes (10 by hand). Add only a few tablespoons of flour at a time if dough sticks to sides, being careful not to add too much.Form into two loaves and place in greased 9x5" pans. Allow to rise in a warm place for about 60 minutes, or 15-30 min. longer if needed to reach ½ to 1-inch above pans (i.e., cold kitchens may need the longer time). Preheat oven to 350 degrees ten minutes before rising time is done.Bake for 30 minutes, rotating halfway through if needed.Immediately remove from pans to cool on a rack. Allow to completely cool before slicing.
