Tropical, vibrant, and naturally sweet, this artisan boule folds luscious pieces of dried mango and a hint of lime zest directly into a high-hydration sourdough crumb. The inclusion of dried fruit, which is pre-hydrated to prevent it from robbing the dough of its moisture, creates sweet, chewy pockets within a beautifully soft interior, all wrapped in a crisp, deeply caramelized crust.

Method

Step 1 – Levain / Starter Prep (Morning Of)
  1. 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.
  2. 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.
Step 2 – Mango Hydration & The Flour Autolyse
  1. 3:30 PM – Pre-Hydrating the Fruit: Place your 80g of chopped dried mango cubes into a small bowl and submerge them completely in warm water. Let them soak for 1 hour to soften.
    2. *Note: Skipping this step means the dried mango will act like a sponge inside your bread, sucking moisture straight out of the surrounding dough and leaving you with dense, dry patches.*
  2. 4:30 PM – Draining and Drying: Pour the soaked mango into a strainer, then spread the pieces across paper towels. Pat them completely dry; surface moisture will create slick barriers that prevent the dough layers from bonding during lamination.
  3. The Flour Hydration: In your stand mixer bowl, combine the 207g of baseline water with 270g of bread flour and 30g of whole wheat flour. Mix with a heavy spoon or your hands just until a shaggy, raw dough mass forms. Cover the bowl and let it rest for 1 full hour to complete the autolyse, activating natural gluten development.
  4. 5:30 PM – Levain Integration: Pour 60g of your mature, peak-ripened levain directly over the autolysed dough. Mix on low speed for 2 to 3 minutes until the starter is completely incorporated. Cover and let the dough rest for 30 minutes.
Step 3 – Bassinage, Fruit Lamination & Warm Fermentation
  1. 6:00 PM – Salt and Bassinage Addition: Sprinkle the 6g of fine sea salt and the optional lime zest evenly over the dough surface, then pour in the reserved 18g of extra cold water. This bassinage process adds a secondary splash of liquid to tighten the gluten network while bringing the total hydration safely to 75%.
  2. 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 74–78°F (23–26°C).
  3. 6:30 PM – The Mango Lamination: Mist your work surface lightly with water and wet your hands. Tip the dough onto the counter and gently stretch it outward horizontally and vertically as thin as you can go without ripping it. Spread your plumped, bone-dry mango pieces uniformly across the entire surface of the stretched dough sheet. Fold the dough cleanly like a letter into thirds, roll it up into a compact package, and place it back into a clean proofing container. Let rest for 45 minutes.
  4. Progressive Structural Folds: Continue building vertical dough strength around the fruit inclusions by executing regular stretch-and-folds spaced 45 minutes apart: 1st fold at 7:15 PM, 2nd fold at 8:00 PM, and the 3rd/final fold at 8:45 PM. Be gentle to avoid tearing the dough skin over the fruit chunks.
  5. Final Bulk Proof: Following the final fold, let the dough proof undisturbed for 30 minutes at 76–80°F (23–26°C). Look for a distinct lightness, small surface bubbles, and a 40% to 50% volume expansion.
Step 4 – Tension Shaping & Cold Retard
  1. 9:15 PM – Preshaping: Transfer the fermented 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 loose round ball, and let it rest uncovered on the counter for 30 minutes to relax the gluten mesh.
  2. 9:45 PM – Final Shaping: Dust the top with a little more flour and use a scraper to flip it over floured-side down. Pull the side closest to you up, pull the right two corners over to the left, fold them up into the half of the dough, and repeat on the opposite side. Roll the dough tightly away from you into a smooth, taut, high-tension round boule or log shape.
  3. Basket Transfer & Cold Retard: Place the shaped loaf seam-side up into a prepared proofing basket heavily dusted with flour. 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.
Step 5 – The High-Heat Tropical Bake
  1. 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.
  2. 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.
  3. 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.
  4. 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, deep golden-brown color with deeply caramelized spots where the fruit sugars peek through. Transfer the baked loaf onto a wire rack and let it cool completely for at least 2 hours before slicing.

Notes

- **The Science of Rehydrating Dried Fruit:** Dried mango is highly hygroscopic, meaning it greedily pulls moisture from its surroundings. If you laminate bone-dry mango chunks into your dough, they will steal water directly from the gluten network during fermentation. This creates pockets of tight, dry, un-risen bread dough immediately surrounding the fruit. Soaking the mango first ensures it stays plump and juicy without throwing off the internal hydration of your loaf.
-**Why Sliced Fruits Require Lamination:** Chunky, heavy inclusions like dried mango pieces should never be mixed during the initial autolyse or primary mixing stages. The sharp edges and weight of the fruit chunks would physically slice through fragile, developing gluten strands, compromising the structural vertical strength necessary for a good oven spring. Waiting until the dough has achieved robust elasticity, stretching it thin via water lamination, and folding the fruit inward ensures it stays perfectly suspended without collapsing your crumb structure.
- **Managing Sugar Caramelization on the Crust:** Mangoes contain high levels of natural fructose. During the final shaping and baking cycles, any fruit pieces that end up sitting directly on the exterior skin of the loaf will brown much faster than the rest of the dough. These spots will bake into a deep, rich mahogany or near-black color under 500°F heat. This is not a burnt crust; it is caramelized fruit sugar, which adds a wonderful dulce-de-leche style depth to the flavor profile.
- **Cooling Before Slicing is Non-Negotiable:** Fruit-filled sourdough loaves require a long, uninterrupted cooling cycle of at least 2 hours before you cut into them. Hot mango pieces act like small, molten pockets of jam while warm; cutting the bread too early will cause the hot fruit sugars to smear across the crumb, making the interior wet, gummy, and sticky.
