Steps

Before you start

Activate your sourdough starter 4–6 hours ahead (or overnight if using cold retard)
Have all ingredients at room temperature before mixing
Preheat oven to 475°F (245°C) 45 minutes before baking
Line a Dutch oven with parchment paper or preheat it empty

1
Caramelize the plantain
- Heat 1 tablespoon (15 ml) of the olive oil in a large skillet over medium-high heat.
- Once shimmering, add the diced plantain cubes in a single layer.
- Let them cook undisturbed for 2–3 minutes until the bottoms are deeply golden, then stir and continue cooking for another 2–3 minutes until the edges are caramelized and tender.
- The plantain should be slightly yielding but still hold its shape.
- Transfer to a plate and let cool to room temperature; you should have about 1.5 cups.

Ready when: Plantain cubes are golden-brown at edges and tender throughout
Tip: Don't stir too early or too often—let the pieces caramelize and develop color for deeper flavor.
2
Mix dough
- In a large bowl, whisk together the bread flour, all-purpose flour, turmeric, garlic powder, and oregano.
- Make a well in the center and add the active sourdough starter and water.
- Mix with a dough whisk or your hand until all flour is incorporated and you have a shaggy, sticky dough with no dry pockets.
- Cover the bowl loosely with a damp kitchen towel.

Ready when: All flour is wetted and dough is shaggy with no dry bits
Tip: Don't knead yet—just mix until the flour is fully incorporated.
3
Autolyse rest
- Let the dough rest, covered, for 30 minutes at room temperature.
- This allows the flour to fully hydrate and begins developing gluten structure without mechanical work.

Tip: The autolyse step is essential for sourdough; it improves extensibility and final crumb structure.
4
Add salt and laminate
- Uncover the dough and sprinkle the sea salt over the top.
- Wet your hand with water and pinch and fold the dough toward the center, rotating the bowl as you go, for about 1 minute until the salt is incorporated.
- The dough should be slack and wet.
- Now perform a lamination: wet your work surface, turn the dough out onto it, and gently stretch it into a large thin sheet (8×10 inches).
- Scatter the cooled caramelized plantain evenly over the surface, then fold the dough in thirds as if folding a letter, gently press down to seal, give it a quarter turn, and fold in thirds again.
- Transfer the dough back to the bowl, seam-side down, and cover.
+ Show details− Hide details
Ready when: Plantain is evenly distributed throughout and dough is cohesive
Tip: Lamination is gentler than traditional kneading for sourdough; it builds strength while keeping the dough extensible.
5
Bulk fermentation—first series
- Cover the dough and let it rest for 30 minutes.
- Then perform a coil fold: wet your hand, reach underneath the dough to grab the bottom, lift it up and fold it over the top toward the center.
- Rotate the bowl 90 degrees and repeat three more times (four folds total, each from a different cardinal direction).
- The dough should become smoother and slightly tighter.
- Cover and repeat this sequence (30-minute rest plus four coil folds) three more times over the next 2 hours, for a total of four rounds of folds.
+ Show details− Hide details
Ready when: Dough is roughly doubled, jiggly, and holds gentle indents when poked
Tip: Coil folds are gentler than stretch-and-fold and help distribute gas evenly. By the final fold, the dough should feel noticeably stronger.
6
Check fermentation progress
- After the fourth set of folds, check the dough's readiness by performing the poke test: gently poke the dough with a floured finger.
- If the indentation springs back slowly (taking 1–2 seconds) and leaves a slight dimple, the dough is ready to shape.
- If it springs back instantly, bulk fermentation needs 15–30 more minutes; if it doesn't spring back, you may have overfermented slightly (it will still bake well, but watch carefully).
+ Show details− Hide details
Ready when: Poke test shows slow recovery with a slight permanent dimple
Tip: Room temperature affects fermentation speed significantly; cooler kitchens may need 30 minutes longer.
7
Shape the dough
- Turn the dough out onto a lightly floured work surface.
- Pre-shape it gently into a round by folding the edges toward the center and under to create surface tension, then let it rest seam-side up for 15 minutes.
- This rests the gluten before final shaping.
- After resting, perform the final shape: flip the dough seam-side down, fold the top third down toward you, press firmly, then fold the bottom third up and seal.
- Rotate the dough 90 degrees and repeat (right third in, left third in, seal).
- Finally, roll the dough away from you, sealing as you go, until it forms a tight log.
- Flip seam-side up into a well-floured banneton basket.

Ready when: Dough is a smooth, tight log with the seam facing up
Tip: Adequate tension on the surface helps the bread rise up rather than spreading. Don't deflate the dough during shaping.
8
Final proof—cold retard
- Cover the banneton with a plastic bag or wrap and place in the refrigerator for 12–16 hours.
- A long, cold retard develops flavor and makes scoring easier.
- You can also proof at room temperature for 2–3 hours if needed, though cold proofing is preferred for sourdough.
+ Show details− Hide details
Ready when: Dough should hold the shape of the banneton with a slight indent when gently poked (cold test)
Tip: The cold retard is your friend: flavor improves, scoring is easier, and timing is more forgiving.
9
Preheat Dutch ovenOven 475°F / 245°C
- About 45 minutes before baking, preheat your oven to 475°F (245°C).
- Place a Dutch oven with the lid on the lowest oven rack.
- The vessel needs to be thoroughly preheated so it can trap steam and create a crispy crust.
+ Show details− Hide details
Ready when: Oven thermometer confirms 475°F (245°C) and Dutch oven is very hot
Tip: A properly preheated Dutch oven is essential for a bold, crispy crust on your sourdough.
10
Score and loadOven 475°F / 245°C
- Carefully remove the hot Dutch oven from the oven.
- Line it with parchment paper if it doesn't already have a liner.
- Turn your cold dough out of the banneton onto the parchment, seam-side down.
- Using a sharp lame, serrated bread knife, or clean razor blade, score the top with one long diagonal slash or an X, cutting about ½ inch (1.3 cm) deep.
- These cuts guide the oven spring.
+ Show details− Hide details
Ready when: Dough is scored with clean, deliberate cuts that open slightly
Tip: A cold dough is much easier to score without tearing. Move quickly to minimize heat loss from the Dutch oven.
11
Bake coveredOven 475°F / 245°C
- Set the parchment and dough into the hot Dutch oven.
- Cover it with the lid and bake at 475°F (245°C) for 20 minutes.
- The closed vessel traps steam, which gives the bread its characteristic crispy, golden crust and helps the dough expand dramatically.
+ Show details− Hide details
Ready when: Bread is visibly puffed and starting to turn pale gold
Tip: Do not lift the lid during this phase; you will release the steam and compromise the crust.
12
Bake uncoveredOven 475°F / 245°C
- Carefully remove the lid and continue baking for 22–25 minutes until the bread is a deep golden-brown all over, with the turmeric giving it a warm amber hue.
- The bottom should sound hollow when tapped.
- The internal crumb temperature should reach 205–210°F (96–99°C).
+ Show details− Hide details
Ready when: Crust is deep golden-amber, bottom is hollow when tapped, internal temperature 205–210°F (96–99°C)
Tip: The turmeric will make the crust appear darker than a plain sourdough; use temperature and the hollow-tap test as your guides rather than color alone.
13
Cool completely
- Remove the bread from the Dutch oven and place it on a wire rack in a cool spot.
- Let it cool for at least 1 hour before slicing.
- The interior continues to set as it cools, and the crumb structure will be much cleaner when fully cooled.
+ Show details− Hide details
Ready when: Bread is at room temperature and feels light and crispy on the outside
Tip: Cutting into a warm loaf will tear the crumb; patience pays off in a cleaner slice.

Tips

For the deepest plantain caramelization and best texture, use a medium or medium-high skillet and let the cubes rest in the hot pan; moving them too frequently prevents browning.
The long cold retard (12–16 hours) is the secret to superior flavor: cold fermentation produces organic acids and develops complex sourdough character that fast, room-temperature proofing cannot replicate.
If your sourdough starter is less vigorous (rises slower), add an extra 30 minutes to bulk fermentation or proof until the poke test passes, rather than timing strictly.
This bread pairs beautifully with Caribbean beans, stewed meats, or fresh cheese; it also makes excellent sandwiches with roasted vegetables and avocado.

Make ahead

The dough can be shaped and refrigerated in the banneton for up to 18 hours; bake straight from the cold. Alternatively, after bulk fermentation, wrap the shaped dough and refrigerate for up to 2 days—the longer cold time deepens flavor but the bread will proof very slowly and may need checking before scoring.

Storage & reheating

Store the cooled loaf in a paper bag at room temperature for up to 3 days (paper keeps the crust crispy while allowing the interior to stay soft). For longer storage, wrap tightly in plastic and freeze for up to 3 months. Thaw at room temperature, then refresh in a 350°F (175°C) oven for 10 minutes to restore the crust. Sourdough stales more slowly than yeasted bread due to its acidity, and the plantain adds moisture that extends shelf life.

Substitutions

yellow plantain, just starting to develop brown spots → green plantain (unripe, starchy) or firm banana. Green plantain will be less sweet; ripe banana will add more sweetness. Adjust cook time when caramelizing—green plantain needs 4–5 minutes per side. The bread will be slightly less complex if using banana.
ground turmeric → 1 teaspoon (2 g) ground ginger or a mix of ginger and 0.5 tsp cayenne pepper. Ginger will give a sharper, spicier note instead of the earthy turmeric warmth. The bread will look pale instead of golden unless you add a pinch of saffron or annatto for color.
dried oregano → dried thyme, dried cilantro, or a mix of cumin (0.5 tsp) and coriander (0.5 tsp). Thyme is more subtle; cumin and coriander will add a warm, toasted Middle Eastern note. Cilantro (if using dried) adds freshness.
extra-virgin olive oil, divided → unsalted butter (same amount) or avocado oil. Butter will add richness and a slight nutty flavor. Avocado oil is neutral and behaves similarly to olive oil.
