What is a Sourdough Starter?
Sourdough starter is a natural culture made from just flour and water, but it quickly grows into something much more powerful. As it develops, this simple mixture captures wild yeast from the air and beneficial bacteria from the flour, forming a living ecosystem that gives bread its rise and signature tang. The yeast and bacteria work together slowly, breaking down starches, creating gases that make the dough airy, and producing organic acids that add rich depth of flavor. Unlike commercial yeast, which offers speed but little character, a sourdough starter is alive and requires regular feedings to stay strong. Many bakers even treat it like a kitchen companion some go as far as naming it because it changes, grows, and rewards consistent care. More than just an ingredient, it is the heart of sourdough baking, the key to achieving the classic airy crumb, golden crust, and complex taste that makes sourdough bread so unique.

Troubleshooting & Fixing Problems in sourdough starter

Hooch (liquid layer) forms: Stir it back in or pour off, then feed immediately.
Unpleasant smell: A tangy smell is normal; rotten or chemical-like odors may mean it’s contaminated—consider starting fresh.
Mold growth: Pink, orange, or black mold means the starter should be discarded.
Regular care and monitoring will help your sourdough thrive and minimize the need for fixes.
