7:00 AM – Starter Initialization: In a clean glass jar, add the 5g of mature sourdough starter culture to 35g of room-temperature water and whisk together thoroughly until completely loose.

Flour Incorporation: Stir in the 30g of all-purpose (or bread) flour and 5g of rye flour. Mix well until no dry pockets remain, cover loosely, and let it sit at room temperature 74–78°F (23–26°C) for 8 to 10 hours until the starter reaches its peak and triples or more in volume.

5:00 PM – The Vibrant Autolyse: In your stand mixer bowl, combine your 200g of freshly blended pink dragon fruit purée with 30g of sweetened condensed milk, 270g of bread flour, and 30g of ultra-grain wheat flour. Mix with a heavy spoon or your hands just until a shaggy, dense pink dough mass forms. Cover the bowl and let it rest for 1 full hour to complete the autolyse, fully hydrating the flour starches directly with the fruit sugars and activating natural gluten chains.

6:00 PM – Levain Integration: Pour 60g of your mature, peak-ripened levain directly over the autolysed dough.

Mechanical Mixing: Secure the bowl in your stand mixer fitted with the dough hook. Mix on low speed for 2 to 3 minutes (or use speed 3 on a KitchenAid mixer for 3 to 4 minutes) until the starter is completely incorporated. Cover and let the dough rest for 30 minutes.

6:30 PM – Salt and Bassinage Addition: Sprinkle the 6g of fine sea salt evenly over the dough surface and pour in the reserved 28g of extra cold water. This bassinage process adds a secondary splash of liquid to tighten the gluten network while bringing the total hydration safely into balance with the dense fruit purée.

High-Speed Emulsification: Mix on a low speed for 2 to 3 minutes (or KitchenAid speed 3 for 5 to 6 minutes) until well incorporated. The dough should pull together into a cohesive ball but remain slightly sticky on the bottom. Cover and leave to rest for 30 minutes at a warm room temperature of 74–78°F (23–26°C).

7:00 PM – First Stretch and Fold: With wet hands, slide your fingers under one side of the pink dough, pull it upward gently to stretch it, and fold it cleanly over the center. Rotate the bowl 90 degrees and repeat on all 4 quadrants. Cover and rest for 45 minutes.

Progressive Structural Folds: Continue building vertical dough strength and managing the active fruit sugars by executing regular stretch-and-folds: 2nd fold at 7:45 PM and the 3rd/final fold at 8:30 PM.

Final Bulk Proof: Following the final fold, let the dough proof undisturbed for 30 minutes at 76–80°F (24–27°C). *Note: The natural fructose from the dragon fruit combined with the condensed milk dairy sugars acts as rocket fuel for wild yeast, accelerating fermentation. Monitor the dough closely; if it expands too quickly, shorten the rest windows between folds to 40 minutes or less.* Look for a distinct lightness, surface bubbles, and a 40% to 50% volume rise.

9:00 PM – Preshaping: Transfer the fermented pink dough out onto your work surface and dust the top lightly with flour. Using your scraper, flip the dough over so the floured side faces down against the counter. Fold the dough cleanly onto itself so that the flour remains entirely on the outside of the loaf, shape into a round ball, and let it rest uncovered on the counter for 30 minutes to relax the gluten mesh.

9:30 PM – Final Shaping: Dust the top with a little whole wheat or bread flour and use a scraper to flip it over floured-side down. Starting at the side closest to you, pull the right two corners of the dough to the left, then fold them up into the half of the dough. Repeat this identical action on the left side. Finally, roll the dough tightly away from you into a smooth, taut, high-tension cylinder (log shape) or round boule.

Basket Transfer & Cold Retard: Place the shaped loaf seam-side up into a prepared proofing basket or a loaf pan lined with a well-floured kitchen towel. Cover it loosely with plastic wrap to trap the moisture. Return the dough to a warm 80°F (27°C) environment for exactly 15 minutes to jumpstart yeast activity, then transfer the covered basket directly into the refrigerator to undergo a slow cold fermentation for 14 to 24 hours.

The Next Day – Oven Preheating: Place your cast-iron Dutch oven and its lid inside your home oven. Turn the temperature 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. Invert it cleanly onto a sheet of parchment paper. Use an ultra-sharp knife or scoring lame to cut a clean decorative slash across the crown.

The Dutch Oven Bake: Carefully transfer the dough into the smoking hot cast-iron pan using the parchment paper handles. Cover tightly with the lid to lock in the escaping steam and bake at 500°F (260°C) for exactly 15 minutes.

The Crisp Finish: Remove the lid to vent the steam, reduce the oven temperature down to 450°F (232°C), and continue baking uncovered for an additional 20 minutes until the crust achieves a beautiful golden-brown color with stunning pink highlights shining through. Transfer the baked loaf onto a wire rack and let it cool completely for at least 2 hours before slicing.
