82% Hydration Slow-Fermented Ciabatta
The Italian answer to the baguette: rougher, wetter, more dramatic. A long fermentation in the biga gives flavor, the high hydration produces the open crumb, and the rustic shape comes from the dough itself, not the baker.

A high-hydration dough wants to flatten on the counter. You manage it with folds instead of kneading, with a banneton instead of free-standing proof, and with a hot Dutch oven or stone that can hold the shape until the spring sets.
A 24 to 48 hour ferment is the professional approach scaled to a home kitchen. The dough rests in the refrigerator for most of its life, gluten develops without effort, and the bake produces a crust and crumb that read as serious bread.
Ingredients
900g total dough. Yields 2 ciabattas, ~400g each baked.

| Water | 390 g | 82% |

Method tips for this style
Don't try to shape ciabatta with your hands. Turn the bulk-fermented dough onto a heavily floured counter, divide with a bench scraper, and lift each portion gently onto the peel. The shape is whatever the dough wants to be.
What to expect
Maximum open crumb with large irregular holes throughout. The crust crisps in pooled olive oil; the interior is light and airy.
