Nine-grain Bread

This comes from More Breaking Bread with Father Dominic (PBS pledge premium!). It calls for "nine-grain cereal mix", but I don't keep such things on hand, so I use oats.

Sponge:
1 cup lukemarm water
2 pks yeast
1 cup bread flour
1/2 cup whole wheat flour
1 t brown sugar

Dough:
1 1/2 cups lukewarm water
2 T veg oil
2 T brown sugar
2 t salt
1 cup nine grain cereal mix (or oats)
1/4 cup millet
1/4 flaxseed
4 1/4-5 cups bread flour, divided

For Sponge: Combine water, yeast, bread flour, whole wheat flour and brown sugar in medium bowl; beat until smooth. Let stand 20 mins or until foamy and doubled in volume.

For Dough: Add water, oil, brown sugar and salt to sponge; beat until smooth. Add cereal, millet and flax seed, stir until incorporated. Add 2 cups bread flour; beat until flour incorporated. Repeat with 2 cup bread flour. Add enough of the remaining bread flour, about 1/4 cup at a time, to form a dough. Dough will be sticky but resist the temptation to add too much more flour.

Turn out dough onto lightly floured surface, Knead 10-12 mins. Rinse and dry the bowl, then oil surface of dough and place in bowl. Cover w/ a clean, dry cloth and let rise about 1 hour or until doubled.

Punch down dough. Knead briefly to expel large air bubbles. Diivde dough in half, the form each half into a loaf. Place loaves in lightly greased 9x5x3 inch loaf pans. Cover with a clean, dry cloth and let rise about 45 mins or until doubled.

About 15 mins before end of risingtime, preheat oven to 375 degrees. Bake loaves 40-45 mins or until golden brown, slide easily from the pan and sound hollow when tapped on the bottom. Cool on wire racks.
