Turn dough out onto a lightly floured surface. Knead in enough of the remaining flour to make a smooth and elastic dough. It should take most, if not all of it.
Place the dough into a lightly greased bowl, turning once to coat both sides. Cover and chill for 2 hours.
Punch dough down and turn out onto a lightly floured surface. Cover and let rest for 10 minutes. Meanwhile, grease an 8x8 pan.
Using lightly floured hands, divide dough into 8 equal pieces.
Shape into balls and arrange in the prepared baking pan. Cover and let rise in a warm place until nearly double in size (about 40 minutes). I put close to the oven and they rose beautifully.
Preheat the oven to 400 degrees. Bake for 20-25 minutes or until golden brown.
Do not over bake. Remove from pan and brush the tops immediately with melted butter before serving. Serve warm.
