Ingredients
  

  • 250 grams sourdough starter, active and bubbly (1 generous cup)
  • 450 grams warm water (1 cup + ¾ cup + 2 Tbsp)
  • 15 grams salt (1 tbs)
  • 615 grams flour (5 cups + 2 tbs)

Instructions
 

  • Mix the dough: In a large bowl, combine the flour, sourdough starter, water, and salt. Mix for about 5 minutes, until a shaggy dough forms. Transfer the dough to a greased bowl, cover, and let the dough rest for 30 minutes to fully hydrate the flour.
  • Stretch and fold: Perform 3 sets of stretch and folds, spaced 30 minutes apart, covering the bowl with a damp towel or plastic between each set.
    To stretch and fold: Dip your hands in water, lift one side of the dough, stretch it upward, and fold it over the center. Rotate the bowl a quarter turn and repeat until all four sides are folded.
  • Bulk Ferment: After the final fold, cover the bowl and allow the dough to bulk ferment for 4–6 hours, until it has risen about 50–75% and looks puffy and bubbly on the surface.
    Overnight option: After the bulk ferment, transfer the covered bowl to the refrigerator and let it ferment overnight. The next day, continue with shaping straight from the fridge.
  • Shape dough: Turn the dough out onto a well-floured surface. Gently divide it into 6 pieces, taking care not to deflate the dough. Transfer the pieces to a parchment-lined baking sheet. Cover and let rest for 45 minutes to 1 hour.
  • Prepare oven: Preheat the oven to 450°F. Place a cast-iron skillet on the bottom rack while the oven preheats. Bring a kettle of water to a boil.
  • Prepare bread: Just before baking, carefully pour the boiling water into the hot cast-iron skillet to create steam. Lightly spritz the ciabatta with water, then place the baking sheet in the oven.
  • Bake: Bake for 25 minutes, until the ciabatta is golden brown with a crisp crust. Transfer to a wire rack and allow to cool before slicing.
