Sponge method
A quick, active preferment stage used mainly to confirm yeast vigour ahead of a same-day bake, rather than for deep flavour development.
- Flour prefermented
- 30-60%
- Hydration
- 80-100%
- Fermentation time
- 1-4h
- Temperature
- 20-28C
Contribution
Flavour: Milder flavour contribution than an overnight poolish or biga, given its much shorter fermentation
Strength: Modest; mainly used to guarantee active yeast performance rather than build significant strength
Extensibility: Slightly increases extensibility versus a direct dough with no preferment stage
Scheduling advantages
- Fits a same-day schedule where an overnight preferment is impractical
Risks
- Short fermentation time limits the flavour complexity gained compared to overnight methods
