Pain Au Levain is a traditional French sourdough bread known for its crusty exterior and chewy interior. Made with simple ingredients like flour, water, salt, and a natural starter, it relies on wild yeast and bacteria for fermentation, giving it a distinct tangy flavor. The bread is typically shaped into a round loaf and baked at high temperatures, resulting in a golden-brown crust. Pain Au Levain is often enjoyed fresh, served with butter, cheese, or used for sandwiches, making it a versatile staple in many households and bakeries around the world.
