Pour 3/4 cup warm water in the bowl of a stand mixer with dough hook attached. Weigh or lightly spoon flour into dry measuring cups and spoons; level with a knife. Add flour to 3/4 cup water; mix until combined. Cover and let stand 20 minutes. Combine remaining 1/4 cup water and yeast in a small bowl; let stand 5 minutes or until bubbly. Add yeast mixture, 4 teaspoons oil, and salt to flour mixture; mix 5 minutes or until a soft dough forms. Place dough in a large bowl coated with cooking spray; cover surface of dough with plastic wrap lightly coated with cooking spray. Refrigerate 24 hours.

Remove dough from refrigerator. Let stand, covered, 1 hour or until dough comes to room temperature. Punch dough down. Press dough out to a 12-inch circle on a lightly floured baking sheet, without raised sides, sprinkled with cornmeal. Crimp edges to form a 1/2-inch border. Cover dough loosely with plastic wrap.
