Salt is Your Sourdough Secret Weapon | Control Your Sourdough's Acidity

Video Description

Is salt killing your sourdough starter? Think again. In this video, we debunk the biggest myths about salt in sourdough and reveal its most overlooked role: a powerful lever to control the flavor and acidity of your bread. Too many bakers are told to fear salt, delaying its addition based on misunderstandings of how it interacts with the complex microbiology of a sourdough culture. We'll dive into the history of salted starters (like the German Monheim process), clarify the real science behind the 'autolyse' method, and explain why delaying salt is really about managing gluten (proteolysis), not saving your yeast. Most importantly, you'll learn how salt dramatically shifts the balance between yeast and Lactic Acid Bacteria (LAB), giving you the power to make your sourdough bread significantly more tangy or wonderfully mild. Turn this humble ingredient into your new secret weapon. In This Video, We Cover: • The myth that salt kills yeast and starters. • Historical uses of salted sourdough (Monheim Salt-Sour Process). • Autolyse vs. Delayed Salt Addition: What's the real reason? • How salt strengthens sourdough's gluten structure. • The science: How salt changes the Yeast to LAB ratio. • Practical Tip: Using salt to make bread LESS sour. • Surprising Trick: Using a pinch of salt to make bread MORE sour. • The connection between salt, temperature, and cold fermentation.
