The Biga.In a jug, whisk together the water & yeast. Leave somewhere warm to go frothy, roughly 5 minutes. 110 g Water, 1 g Dried Active Yeast
In a small mixing bowl, place the 00 flour & the activated yeast. Use your hands to bring together into a rough dough. Make sure not to overwork the biga as this will make it get too warm. Stop mixing as soon as a rough dough forms. 180 g 00 Flour
Cover the bowl with clingfilm & leave to ferment at 15°c - 20°c for 10-12 hours.
The Dough.Half an hour before the biga is ready, place the flour & 200g of water (@25.5°c/78°f) into the bowl of a stand mixer. Using the dough hook, mix until a rough dough forms.Leave to autolyse for 30 minutes. 200 g Water, 270 g 00 Flour
Next, combine the yeast & the 50g of water (@38°c/100°f) then leave to go frothy.
50 g Water, 2 g Dried Active Yeast
In the meantime, use a pair of scissors dipped in water to cut the biga into small pieces. Place this into the autolysed dough along with the activated yeast.
Mix on a medium speed until combined then add in the salt & olive oil.
9 g Maldon Sea Salt, 25 g Olive Oil
Keep mixing on medium speed until the dough passes the windowpane test, roughly 5-10 minutes.
Transfer the dough into a lightly oiled bowl & leave at room temperature for 1 hour, performing a set of coil folds every 20 minutes.If your kitchen is warmer than 26°c/78°f, leave the dough at room temperature for 45 minutes, coil folding every 15 minutes. Cover the bowl with clingfilm, place into the fridge & leave for 12 hours*.*Give the dough at least 10 hours in the fridge but no more than 18 hours. Next, carefully transfer the dough onto a worksurface dusted with plenty of 00 flour. Use a plastic dough scraper to release the dough from the bowl if necessary.
Dust the top of the dough with more 00 flour then use a metal bench knife to push the sides in to form a rectangle roughly 15cm x 25cm.Use the dough knife to cut the dough in half lengthwise then carefully transfer each piece of dough onto a baking tray lined with baking parchment, leaving plenty of space between.I like to use an upside down baking tray as the flat surface makes transferring the dough onto the baking stone easier. Cover the ciabattas with an upside down baking tin/roasting tray & leave to rise for 1-1½ hours. The dough is ready to bake when it has risen slightly. If you press the dough lightly with a fingertip, the indentation will slowly fill back in. If it springs back straight away, it needs to prove for longer. Whilst your ciabattas are proving, preheat an oven to 220°c/200°c fan. (430°f/390°f fan). Place a baking stone or large baking tray in the oven at the same time & leave to preheat for at least 30 minutes.
Fill a spray bottle with cold water.
Once ready to bake, carefully slide the ciabattas onto the baking stone/baking tray (leaving them on the baking parchment), spray the dough generously with cold water then immediately shut the oven dough.Alternatively, when you preheat your oven/baking stone, place a roasting tin onto the bottom of the oven at the same time. When you go to bake the bread, pour 100-200ml of water into the roasting tin just before shutting the oven door. Bake for 20-25 minutes, or until the bread is golden brown & sounds hollow when tapped on the bottom.
Once cooked, transfer the ciabattas onto a wire cooling rack & leave to cool completely.
