DAY 1

​Step 1: Feeding Sourdough Starter

• First thing in the morning, feed your sourdough starter and leave it in a warm spot (ideally, (21-27°C)), semi-covered for 4 hours. Your starter should at least double in volume in this time. If it doesn’t, it may need a couple of good feeds before it’s fit for purpose.

Step 2: Mixing The Dough

• Once the sourdough starter is active and bubbly (and at least doubled in volume), mix the dough. Mix strong white flour, ground flaxseed (flaxseed meal) and salt in the bowl of a stand mixer.
• Pour lukewarm water (note that flaxseed dough will be wet and sticky, but eventually flaxseed will absorb a lot of water into the dry ingredients). Then add the active starter.
• Run the mixer, fitted with a dough hook attachment for 10 minutes, until your dough is smooth and elastic. It does not need to pass the windowpane test just yet (the gluten will continue developing when we fold the dough.

Step 3: Folding and Bulk Fermentation

• Scoop the dough into a large bowl, cover with a damp kitchen towel or plastic wrap and leave it in a warm place (21-27°C) for 30 minutes.
• After 30 minutes, with cold wet hands, perform the first set of coil folds (you may use the stretch and fold method if that's what you're used to). Simply lift the bread dough with both hands from the sides and tuck it under to form a coil (video in the text above). Rotate the bowl a quarter turn and coil again. Cover the bowl again, and let the dough rest for 30 minutes again.
• You should repeat the process every 30 minutes until you have done 4-6 sets of coil folds. Your dough will spread less with every set of folds, and by the end of it, you will have a much less sticky, very soft and elastic dough that has blisters on top of the dough.
• For more information on how to coil fold and when to know when you’ve done enough folding, head to our dedicated article about Sourdough Coil Folds.
• Once all the folds have been completed, cover the dough and let the dough rise at warm room temperature for 3-4 hours to finish bulk fermentation (flaxseed sourdough takes a little while longer that regular sourdough). Your dough should bulk up by about 75% (if it doubles in volume though, don’t worry, you will simply get a little less oven spring). If you are using a see-through glass bowl for bulk fermenting, you should see a lot of activity and bubbles forming at the base and sides of the bowl.

Step 4: Shaping and Cold Retardation

• At the end of bulk fermentation, using a bowl scraper, scoop the dough onto a lightly floured surface. Try and make sure that the smooth top of the dough (the side that is not intact with the bowl) is placed on the floured work surface. Then swiftly fold the four corners of the dough into the centre.
• Flip the dough seam-side down and use your hands to cup and rotate it, pulling it slightly against the surface to form a smooth, tight ball.
• Place the dough ball into a well-floured banneton basket (or any proofing basket alternatives). We recommend using rice flour for dusting your proofing baskets. The smooth side of the sourdough ball should be at the bottom, with the seam at the top.
• Pinch the seam together with your fingers, if the dough starts spreading in the bowl to make sure the dough is tight. Sprinkle with some flour, and cover the dough with a clean fabric napkin or small lightweight tea towel.
• Place the proofing basket in a large plastic bag – it will protect the dough from drying out. Then place the whole thing in the fridge for its final rise (a.k.a. second rise) in the fridge for 12-36 hours.

DAY 2

Step 5: Preheating Dutch Oven

• The next day, place the Dutch Oven in the oven, and preheat it to 240°C (typically, it is the highest temperature home ovens will go to) with the Dutch oven in it. It needs to be piping hot!

Step 6: Scoring Sourdough

• Once the oven is hot, take the dough out of the fridge and out of the bag.
• Invert the dough gently onto a large piece of parchment paper. If your dough was properly bulk fermented and shaped correctly, it should not spread much once inverted.
• Dust the surface of the dough with flour. Using a bread lame or a razor blade, score the dough deeply (approximately 1cm deep) at a 30- 45º angle or a straight line down the middle as shown below.
• One single deep slash is all that’s needed for that sought-after sourdough “ear”.

Step 7: Baking

• Take the hot Dutch Oven out of the oven, take the lid off, and lift the sourdough into it, holding the edges of the parchment paper. Be mindful of how you lift the paper. Sometimes, the scored slash can begin to close up during this process.
• To prevent this, lift the parchment from the sides that won’t push the two edges of the scored dough back together. Or try baking sourdough in an inverted Dutch Oven!
• Place the lid back on the Dutch Oven and place the bread into the hot oven for 25 minutes.
• After 25 minutes, reduce the oven temperature to 200°C, take the lid off, and return the sourdough to the oven for another 25 minutes to form a crispy crust.

Step 8: Cooling

• Once baked, take the Dutch Oven out of the oven. Lift the bread out by holding the corners of the parchment paper. Place the bread onto a wire rack, and slide the parchment paper from underneath the loaf.
• Leave the flaxseed sourdough bread to cool down to room temperature before slicing.
