To make stand-alone rolls, divide the dough into 16 equal pieces. If you want to make soft-sided, pull-apart rolls, divide the dough into 15 pieces. This isn't as challenging as it sounds: first, divide the dough into three equal pieces (about 375g, 14 ounces, each). Pinch off one piece, about the size of a racquetball or handball (75g, 2 3/4 ounces), off each of the three pieces, setting the pinched-off pieces aside; then simply divide what's left of the three pieces into four pieces each. Presto! Fifteen balls of dough. Gently roll the dough balls under your cupped fingers till they're nice and round. Place the 16 dough balls onto a parchment-lined or lightly greased baking sheet or sheets, leaving about 2 inches between them. Or place the 15 dough balls into a lightly greased 9 x 13-inch pan, spacing them evenly in five rolls of three balls each. Cover the pan(s) with a proof cover or lightly greased plastic wrap, and allow the rolls to rise for about 2 hours, till they're quite puffy; the rolls in the 9 x 13-inch pan should be touching (or almost touching) one another. Baking: Bake the rolls in a preheated 350°F oven for 20 to 25 minutes, till they're golden brown. Remove them from the oven, carefully turn them out of the pan -- the pull-apart rolls will come out all in one piece -- and brush them with melted butter, if desired. Serve warm or at room temperature. Yield: 15 or 16 rolls.
