Lightly sprinkle a board or other clean surface with all-purpose flour. Turn the dough out onto the board and sprinkle the top lightly with flour. With floured hands, fold the dough in half, and pat dough out into a 1/3- to 1/2-inch-thick round, using a little additional flour only if needed. Flour again if necessary, and fold the dough in half a second time. If the dough is still clumpy, pat and fold a third time. Pat dough out into a 1-inch-thick round. Brush off any visible flour from the top. For each biscuit, dip a 2-inch biscuit cutter into the reserved flour and cut out the biscuits, starting at the outside edge and cutting very close together, being careful not to twist the cutter. The scraps may be combined to make additional biscuits, although these scraps make tougher biscuits.
