LEVAIN BREAD RECIPES

Steps:

• (night before mixing, 9:00 p.m.)In a small container, mix the Levain ingredients and keep it at a warm temperature overnight.
• (the next day, 7:30 a.m.)Preheat your oven to 350°F (175°C). Spread the 160g walnuts out evenly on a sheet pan and bake for 10 to 15 minutes until they start to take on a little color and become very fragrant. Set aside until bulk fermentation.
• (8:00 a.m)In a medium mixing bowl, add the 600g medium-protein bread flour, 120g whole wheat flour, and 520g water and mix until no dry bits remain. Cover the bowl and let rest for 1 hour.
• (9:00 a.m.)To the mixing bowl holding your dough, add the levain and a splash of water. Mix thoroughly and strengthen the dough for about 5 minutes. Let the dough rest for 10 minutes in the mixing bowl. Add the salt, another splash of water, and mix until incorporated. Strengthen the dough further if necessary until it’s elastic and smooth. Then, slowly add the walnut oil over the course of the next few minutes while stretching and folding until the oil is absorbed and the dough is smooth and shiny. Transfer the dough to a bulk fermentation container and cover.
• (9:30 a.m. to 12:30 p.m.)Before you give your dough its first set of stretch and folds, spread about 1/4 of the mix-ins over the top of the dough. Add the rest of the mix-ins in the same way through the remaining folds for the first set. Perform two more sets of gentle stretch and folds during this 3-hour period, then let the dough rest the remainder of bulk fermentation.
• (12:30 p.m.)Lightly flour your work surface and scrape out your dough. Using your bench knife, divide the dough in half. Lightly shape each half into a round shape. Let the dough rest for 30 minutes, uncovered.
• (1:15 p.m.)Shape the dough into a round (boule) or oval (batard) and place in proofing baskets. Cover the baskets with a reusable plastic bag.
• (1:30 p.m. to 9:00 a.m. the next day)Cover proofing baskets with reusable plastic and seal shut. Then, place both baskets into the refrigerator and proof overnight.
• (The next day, bake at 9:00 a.m.)Preheat your oven with a baking surface or combo cooker/Dutch oven inside to 450°F (230°C).

Steps:

• 1. The night before you want to bake, make the levain starter. Pour 50ml of tepid water into a large mixing bowl. Use your fingers to gently stir in the mature sourdough starter until fully dissolved, then repeat with the flour until smooth and combined.
  2. Leave, covered, in a warm place for at least 8 hours – it’s ready when lots of bubbles appear on the surface and the dough has a milky-sweet aroma.
  3. The next day, to make the final dough, pour 325ml of tepid water into a large mixing bowl and add 100g of the levain, which should float (the remaining levain can be fed and used as a new sourdough starter, or gifted to a friend). Use your fingers to gently stir it into the water until fully dissolved, then repeat with both flours. Cover with a damp cloth and rest in a warm place for 1 hour.
  4. Now add the salt and 25ml of tepid water, scrunching them into the dough until fully combined. Set aside, covered, in a warm place for 30 minutes.
  5. Wet your hand slightly and give the dough four folds in the bowl, one at each ‘corner’. This is one turn. Repeat this process another three times at 30-minute intervals, turning the dough four times in total across 2 hours. After the last turn, cover and leave to rise in a warm place for another 2 hours.
  6. To shape the loaf, tip the dough onto a clean surface and gently dust the top with a handful of semolina flour. Roughly shape into a round, being careful to keep as much air in the dough as possible. Rest, covered, for 30 minutes.
  7. Dust a basket or cane banneton with semolina flour (or you can simply use a medium bowl lined with a clean, floured tea towel). Lightly flour the dough again and flip it over, so the flour side is on the worktop. Set the dough in front of you and gently shape into a round. Turn the dough over, then place it in your floured basket, banneton or tea towel-lined bowl.
  8. Cover the dough with a shower cap (or oiled cling film) and allow to rest for 1 to 2 hours, or until increased in size by a quarter and looking bubbly. Transfer your dough, in its basket or bowl, to the fridge to rise for another 12 to 16 hours, or until bubbly and risen by another quarter.
  9. Place a heavy lidded casserole pot on the bottom shelf of the oven, then preheat to full whack (240ºC/464ºF/gas 9).
  10. Bring your loaf out of the fridge and scatter semolina over the top. Working carefully, remove the hot pot from the oven, take off the lid and gently tip your dough out into the pot, so now the pattern should be the right way up. Score it with a sharp knife, holding it at a 40 degree angle to the surface of the dough for the best slashes, then carefully cover and return to the oven.
  11. Reduce the temperature to 230ºC/446ºF/gas 8 and bake for 30 minutes. Carefully remove the lid and bake for a final 20 minutes, or until a malted golden brown. Remove to a wire rack to cool.
