Open Crumb - sourdough recipe card and loaf verdict
Clean
Paste a sourdough recipe and how the last loaf came out: free baker's percentages (hydration with the starter, salt, starter and whole-grain share), a bulk-fermentation estimate from your kitchen temperature, a schedule and scaling on a stack of recipe cards; one metered read gives a bake / adjust / rework verdict, a loaf diagnosis, re-checked weight changes and the method with cues.
