Mix
- 1.In a large bowl, whisk together the flour, salt, and yeast. Add the water (room temperature, ~70°F / 21°C — cool to keep the long ferment from racing).
- 2.Stir with a sturdy spoon or wet hand for ~30 seconds until just combined. No dry pockets. The dough will be sticky, shaggy, and look completely unpromising. That is correct.
- 3.Cover the bowl with plastic wrap or a tight-fitting lid. Leave on the counter (NOT in the fridge) for 12–18 hours. The dough does all its development unattended.
Use bread flour for a chewier crumb; AP flour for a softer one. Both work. The original Lahey recipe is AP-only.
