Using a bowl scraper, cut the dough ball almost in half, stopping just before the bottom, leaving about 1/8 inch (3 mm) uncut; keep the halves attached (A). Make a second cut across the first, also stopping just before the bottom (B). Using your thumb and forefinger, press two opposite sections toward the center to square off the sides (C). Repeat with the remaining two sides to make a square roll (D).
