What is the science of sourdough?

The transformation of dough into a loaf is chemistry in action. Sourdough differs from most bread in that it contains no baker’s yeast, relying instead on a fermented “starter” of water and flour to provide lift. This also provides its sour flavour and chewy texture.

Is it hard to maintain sourdough starter?

Your starter will grow to at least double in size, sometimes more, and you’ll need a jar to accommodate this. You can cover it loosely with a lid, plastic wrap, or even a small cloth.

What is the best ratio for sourdough starter?

The best way to ensure a healthy and thriving starter is to feed at peak—the point at which yeast activity is high but the starter isn’t yet proteolytic and gluten-weakening. For instance, at a feeding ratio of 1:3:3 or 1:4:4, a healthy starter should peak in at most 8-12 hours.

Can you use too much starter in sourdough bread?

Sourdough starter is a live food, it has active yeast and bacteria. If you use too much starter it will consume the sugars and nutrients in the dough mix too fast. If this happens there will be a lack of bubbles that should be there due to fermentation.

How to make a sourdough starter?
