3. Turn dough out onto a lightly floured surface. Knead until smooth and elastic (about 10 minutes); add enough of remaining bread flour 1 tbsp at a time to prevent dough from sticking to hands. Dough will feel tacky. Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°F), free from drafts, 2 hours or until doubled in size. Press 2 fingers into dough. If indentation remains,the dough has risen enough.
