Rustic Bread

Using your hands, mix bread flour, salt, yeast, and 2 cups (450 grams) room-temperature water in a medium bowl. Lightly knead, grabbing corners of dough, gently pulling upward, and pushing toward the center, until dough comes together. Dust another bowl with all-purpose flour and transfer dough to bowl. Cover with plastic wrap and chill 12–18 hours.
Turn out dough onto a lightly floured work surface, dust with flour, and press into a 8x5" rectangle. Fold rectangle in half lengthwise, then roll up tightly at narrow end (like a burrito). Place both hands on top of dough; working against friction of work surface, pull gently down toward yourself to create a rounded boule shape.
Transfer dough to a lightly floured parchment-lined rimmed baking sheet and cover loosely with a clean flour-dusted towel. Let rise at room temperature 4 hours, or chill 6–12 hours.
One hour before baking, arrange rack in middle of oven; preheat to 500°F. After dough has risen, slash dough with a razor blade or very sharp knife in 3 parallel slits at least 1/4" deep. Transfer baking sheet to oven, reduce oven temperature to 450°F, and bake bread until crust is very brown and an instant-read thermometer registers 190–200°F, 30–40 minutes. Let cool before slicing, about 2 hours.
