10:00 PM – Levain Initialization: In a small glass jar, whisk the 5g of starter culture into 35g of room-temperature water. Stir in 35g of bread flour until no dry spots remain. Cover loosely and let rest at a stable room temperature of 74–78°F (23–26°C) overnight for 8 to 10 hours until it bubbles and triples in volume.

The Flaxseed Soaker: In a dry skillet over medium heat, toast the 35g of whole flaxseeds for 3 to 5 minutes until they release a nutty aroma and begin to pop. Transfer them immediately to a small heatproof bowl, pour the 70g of boiling water directly over them, and stir. Cover tightly and let sit at room temperature overnight to completely absorb the water and form a gelatinous gel.

8:00 AM – The Artisan Autolyse: In your stand mixer bowl, combine the 172g of baseline water with all 265g of bread flour. Mix with a heavy spoon or your hands just until a shaggy, raw dough mass forms. Cover the bowl securely and let it rest for 1 full hour to allow the wheat proteins to self-hydrate and kickstart natural gluten development.

9:00 AM – Levain and Salt Integration: Add the 60g of active, peak-ripened overnight levain over the autolysed dough. Fit your mixer with the dough hook and mix on low speed for 2 to 3 minutes until smooth. Sprinkle the 6g of fine sea salt evenly across the surface and continue mixing on medium speed for an additional 3 to 4 minutes until the dough pulls away from the sides and forms a tight, cohesive ball.

Flaxseed Emulsification: Turn the mixer down to low speed and gradually add the entire prepared gelatinous flaxseed soaker into the dough matrix. Mix continuously for 4 to 5 minutes until the slippery seeds are completely and uniformly distributed throughout the dough.

9:45 AM – The Lamination Stretch: Tip the sticky dough out onto a lightly misted or wet work surface. Using wet hands, gently stretch the dough out horizontally and vertically into a large, thin rectangular sheet. Fold the dough like a letter into thirds, then roll it into a neat cylinder to smoothly layer the seeds internally. Place it into a clean proofing container.

Structural Stretch & Folds: Cover the container and let it bulk ferment at a warm 76–80°F (24–27°C) for 3 hours. During the first 2 hours, perform 3 gentle rounds of coil folds or stretch-and-folds spaced 40 minutes apart to build high vertical tension. The dough should look visibly aerated, holding its shape with clear gas bubbles on the surface by the end of bulk proofing.

12:45 PM – Preshaping: Gently ease the dough out onto a clean counter. Use a dough scraper to round it into a loose ball. Let it sit uncovered for 20 minutes to allow the gluten network to relax.

Final Tension Shaping: Dust the top with flour and flip it over. Pull the bottom edge up, fold the sides inward like an envelope, and roll the dough tightly away from you into a high-tension log or round boule. Place the shaped dough seam-side up into a prepared proofing basket heavily dusted with rice flour.

1:15 PM – Cold Retard Setup: Cover the basket with plastic wrap to seal in the moisture. Place it directly into your refrigerator to undergo a slow cold fermentation for 14 to 24 hours to develop complex, tangy flavor profiles.

7:00 AM – Oven Preheating: Place your cast-iron Dutch oven and its lid on the center rack of your oven. Turn the heat up to 500°F (260°C) and let it preheat thoroughly for 45 minutes to 1 hour.

Inversion and Scoring: Remove the cold dough basket directly from the fridge. Lay a piece of parchment paper over the base, flip the basket over cleanly, and lift it away. Use an ultra-sharp scoring lame to cut a long, shallow slash down the center at a 45-degree angle to ensure a dramatic "ear" forms during baking.

The Dutch Oven Bake: Carefully remove the scorching hot Dutch oven lid. Drop the dough inside using the parchment paper handles. Replace the lid tightly and bake at 500°F (260°C) for exactly 15 minutes to trap the steam.

The Crisp Finish: Remove the lid to vent the steam, reduce the oven temperature to 450°F (232°C), and continue baking uncovered for 20 more minutes until the crust turns a deep, blistered mahogany brown. Cool completely on a wire rack for at least 2 hours before slicing.
