1. Place first 3 ingredients in bowl of a heavy-duty electric stand mixer; beat at low speed (using a dough hook attachment) until blended. Gradually add water and oil in a slow, steady stream, and beat at low speed 3 minutes. Beat at high speed 5 minutes.
2. Cover dough with plastic wrap; let rise in a warm place (85°), free from drafts, 1 1/2 to 2 hours or until almost doubled in bulk and dough is springy when lightly touched. Punch dough down, and shape into a large ball; cut dough into 4 equal pieces.
3. Roll each piece of dough into a ball. Stretch top of dough around outside of ball, and pinch the edges together, forming a smooth ball.
4. Place dough balls on a lightly greased baking sheet, and dust with flour. Cover with a damp towel. Let stand in a cool place 1 hour.
