Step 3) Gradually add enough remaining flour to make a soft dough. Dough should form a ball and will be slightly sticky. Knead** on a floured surface, adding additional flour if necessary, until smooth and elastic, about 4 minutes. Cover; let rest on floured suface 10 minutes. (If using Pizza Crust Yeast, omit 10-minute rest.) Divide dough into 8 portions; cover.
