First Rise (Bulk Fermentation): Place the dough in a lightly greasedbowl, cover it with a damp cloth, and let it rise at room temperature for 4-6hours, or until it has doubled in size.
Shape the Dough: After the first rise, punch down thedough to release any air bubbles. Shape it into a loaf or your desired shapeand place it in a greased loaf pan or on a baking sheet.

Bake: Bake the bread in the preheated ovenfor 30-35 minutes, or until the crust is golden brown and the bread soundshollow when tapped on the bottom. Oven heat can fluctuate, so some loaves ofbread may require up to 60 minutes of baking. Always use a thermometer toensure the center of the loaf reaches between 195°F and 200°F for perfectdoneness.
Cool: Allow the bread to cool on a wire rack beforeslicing and serving.
