SPROUTED WHEAT SOURDOUGH CIABATTA

Steps:

• MIXING AND BULK FERMENTATION
• Combine all the ingredients in a stand mixer with dough hook attachment. Mix on low speed about a minute until combined and then scrape down the sides. Then mix on medium-low speed for about 5 minutes and then transfer the dough to a clean bowl. Alternately or additionally, mix in a bowl with a stiff spatula and then with the Rubaud Method for 2-10 minutes (the longer time is if you take breaks). After mixing, note the time and room temperature if you like to track fermentation this way.
• Cover and let the dough rest for 30 minutes.
• Do three gentle stretch and folds, spaced 25-45 minutes apart. Use damp fingertips or a dough scraper to pull the dough from the sides of the bowl and fold it over (four sides, twice around). Cover after each stretch and fold.
• Let ferment until bubbly and roughly doubled. This was a little over 4 hours from mixing in summer house temps (75-78F).
• SHAPING
• Flour your countertop, then scrape the dough out of the bowl.
• Flour your hands and gently slide your fingers under the dough from all sides to pull it outward into a square shape about 1/2 an inch thick. Do not flour the surface of the dough as this will be the interior of your slippers.
• Using a bench scraper, fold the rectangle of dough in half on itself. Then cut the dough in pieces. I went with five small slippers, almost like large rolls. Of note I did not do a bench rest and reshape. It was about 10 minutes from bowl to couche.
• Using a bench scraper and your free hand, transfer the slippers to the channels of a heavily floured couche or tea towel. The slippers will scrunch up a bit as you gather them, but you can adjust and stretch them out again as you lay them in the couche.
• Loosely cover the slippers with the couche itself or with another tea towel.
• PROOFING AND OVEN PREP
• Let the slippers proof for about 30 minutes at warm room temperatures, longer in cool temps.
• If you have a baking stone or steel, put it in the oven. You can also cook the slippers on a metal cookie sheet. (Do not use a dark non-stick surface because of the high oven temperature.)
• Prepare to create steam early in the baking process. You can put a cast iron pan on the shelf under the baking stone. Or you can create a drip system by putting an aluminum pan with a pinhole in the oven under the stone, and a metal cookie sheet on the base of the oven. When making the pinhole, test over your sink that water drips through it about 1-2 drops a second. My heating element is exposed on the bottom of my oven, so the aluminum pan drips onto the bottom of the oven rather than a cookie sheet, which works fine too. (See gallery for photo of setup.)
• Preheat your oven and stone to 500 F for 30 minutes as the dough proofs. If you are baking on a cookie sheet, a 15 minute preheat should be enough.
• BAKING
• When proofing is complete, flip the slippers onto pieces of parchment paper, and slide the slippers onto your preheated stone. You can use a pizza peel or a cold upside down cookie sheet to transfer the slippers.
• Immediately pour a cup of water onto the aluminum tray or cast iron pan that is under your stone, and quickly close the oven door to trap the steam.
• Bake at 500 F for 10 minutes. Then remove the parchment paper and rotate the slippers 180 degrees if your oven seems to brown unevenly.
• Bake an additional 5-10 minutes at 450 F.
• After baking, turn off the oven, crack open the door a couple of inches, and leave the slippers in the oven for another 5 minutes. This will make the crust crunchier.
• Internal temperature should be about 205 F.
• Let cool on a rack for about one hour before slicing.
