Sourdough Baking Tips
Use a digital scale
Sourdough is all about ratios. A scale is essential — volume measurements are too inconsistent for reliable results.
Feed before baking
Use starter at its peak (when it's doubled and bubbly). Feed it 1:2:2 about 4-6 hours before you plan to mix dough.
Autolyse first
Mix flour and water, let rest 20-60 minutes before adding salt and starter. This develops gluten with less kneading.
Watch the dough, not the clock
Rising times vary with temperature. Let the dough double (or reach 50% increase) regardless of how long it takes.
