Clarity before cleverness
Sourdough recipes often hide a little flour and water inside the starter. This tool makes those quantities visible, then helps you answer three questions: what is my hydration, how much water reaches my target, and how do I scale the recipe?
A tool you can check
The calculation method and a worked example are public. Inputs are processed in your browser. There is no account, recipe upload or subscription needed. We do not claim that the tool has been professionally bake-tested or that a particular percentage will guarantee a successful loaf.
Built with assistance
AI tools assisted with code, explanatory text and translations. Mathematical checks accompany the source package. The site does not invent a baker’s biography or independent certification. Corrections can be sent through the contact page once the operator publishes an address.
