Levain is a key ingredient and process in professional baking that refers to a natural fermentation starter made from flour and water. It's similar to sourdough starter but specifically used in French baking traditions. Bakers use levain to make bread rise naturally without commercial yeast, resulting in products with more complex flavors and better texture. This traditional method is highly valued in artisanal bakeries and high-end restaurants. The term might appear as "natural starter," "mother starter," or "chef" in some job descriptions.
