This visually stunning artisan loaf features a vibrant, golden-yellow interior crumb courtesy of ground turmeric, beautifully contrasted by a rich, texturized crunch from toasted pumpkin seeds. This bread balances the warm, slightly earthy notes of turmeric with a classic sourdough tang, finished with an incredibly crisp crust.
10:00 PM – Starter Build: In a small glass jar, add your 5g of starter culture to 35g of water and whisk together cleanly. Stir in 30g of all-purpose or bread flour and 5g of rye flour. Mix thoroughly, cover loosely, and let it sit at room temperature 74–78°F (24–26°C) overnight for 8 to 10 hours until the starter reaches its peak and at least triples in volume.
Pumpkin Seed Prep: In a dry skillet over medium heat, toast the 50g of pumpkin seeds for 3 to 4 minutes until they become fragrant and begin to pop slightly. Transfer them immediately to a small bowl, cover with warm water, and let them soak overnight. (Soaking prevents the dry seeds from robbing moisture directly from your dough crumb later).
Day 2 – The Golden Autolyse, Bassinage, and Core Mixing
8:00 AM – The Turmeric Autolyse: In a large bowl, thoroughly whisk together the 270g of bread flour, 30g of whole wheat flour, and 4g of ground turmeric powder until the flour turns a uniform pale yellow. Pour in 207g of water and mix with a spoon just until all dry patches entirely disappear. Cover tightly and let it autolyse on your counter for 1 full hour.
9:00 AM – Sourdough Starter Integration: Add 60g of your active overnight starter peak directly into the golden autolysed dough. Knead by hand or mix on low speed for 2 to 3 minutes until the starter is completely incorporated. Cover and let rest for 30 minutes.
9:30 AM – Bassinage & Salt Incorporation: Add your 6g of salt along with the remaining 30g of cold bassinage water into the bowl. Squeeze and knead the dough for 3 to 5 minutes until the extra liquid is fully absorbed and a cohesive, smooth dough forms. Cover and let rest for 30 minutes at a stable warm temperature of 74–78°F (23–26°C).
Lamination Inclusions & Bulk Fermentation Folds
10:00 AM – Seed Lamination: Drain your soaked pumpkin seeds thoroughly and pat them dry with a paper towel. Spray your clean work surface lightly with water and wet your hands. Gently tip the yellow dough out and stretch it out as thin as possible across the table without tearing the delicate matrix. Scatter the pumpkin seeds evenly over the entire surface. Fold the dough cleanly over onto itself into a neat package to trap the seeds, return it to your bulk container, and let rest for 45 minutes.
10:45 AM – 1st Stretch & Fold: Wet your hands slightly. Lift one side of the dough up cleanly from the container edge and fold it directly over the center. Repeat this action for all four quadrants of the dough mass to build structured vertical strength and distribute the seeds. Cover and let rest for 45 minutes.
11:30 AM – 2nd Stretch & Fold: Execute your second structured round of quadrant folds to continue organizing the expanding gluten network. Cover and let rest for 45 minutes.
12:15 PM – 3rd Stretch & Fold: Execute the third and final stretch-and-fold round. Cover and let the dough proof completely untouched for 30 minutes at a warm 76–80°F (24–28°C). The dough should look visibly lighter, show distinct surface bubbles, and hit a clean 50% volume rise.
Preshaping, Tension Rolling, and Cold Retard
12:45 PM – Preshaping: Gently tip the expanded dough out onto your work surface and dust the top lightly with flour. Flip the mass over so the floured side faces directly down. Fold the outer edges cleanly onto itself so that the raw flour coating remains entirely on the outside of the loaf. Round the dough into a loose ball and let it rest on your counter completely uncovered for 30 minutes to relax the gluten network.
1:15 PM – Final Shaping: Dust the top of the resting dough round with flour. Use a dough scraper to flip it over onto your counter so the floured side faces down. Starting at the edge closest to you, pull the two right corners of the dough outward and fold them up into the center. Repeat this exact matching movement across the left side. Roll the dough tightly away from you, shaping it into a perfectly smooth, taut, uniform boule or batard.
Basket Stabilization & Fridge Retard: Transfer the shaped roll seam-side up into your well-floured proofing basket. Cover with plastic wrap and return the basket to a warm 80°F (27°C) spot for exactly 15 minutes to stabilize. Slide the basket directly into your refrigerator to rise slowly for 14 to 24 hours of cold fermentation retard at a stable 40°F (4°C).
Day 3 – Blazing Cast Iron Bake
Next Morning – Preheating: Preheat your oven to 500°F (260°C). Place your cast iron pan and lid onto the middle rack to heat up thoroughly for 45 minutes to 1 hour.
Scoring & Loading: Remove the cold golden dough basket from the fridge. Flip it over gently onto a sheet of parchment paper and score the smooth surface with one clean, long, deep cut using a sharp lame or razor blade. (Optional: You can press a few extra raw pumpkin seeds into the crust around the score line for visual effect).
The Steam Bake: Transfer the dough carefully onto the smoking hot cast iron pan base, drop the heavy lid down tightly to lock in the steam, and bake at 500°F (260°C) with the lid on for exactly 15 minutes.
The Open Bake: Carefully lift the hot lid off to expose the loaf, lower the oven temperature to 450°F (232°C), and continue baking bare for an additional 20 minutes until the crust turns an incredibly deep golden-brown hue. Let cool on a wire rack for 2 full hours before slicing!
Why Pre-Soaking the Seeds is a Absolute Necessity: Adding raw or roasted dry seeds directly into an artisan sourdough mix will quickly ruin your crumb texture. Dry seeds are incredibly thirsty and will act like tiny sponges, pulling hydration straight out of the surrounding dough matrix. This creates dense, dry, and gummy pockets immediately surrounding the inclusions. Pre-soaking the pumpkin seeds overnight ensures they are fully saturated and won't disrupt your dough's hydration.
The Golden Properties of Turmeric in Sourdough: Beyond providing a magnificent, deep marigold color to your interior crumb, turmeric root powder carries a warm, subtle woodsy profile that complements the natural lactic tang of a long sourdough fermentation. Turmeric is also a natural antioxidant, though it can slightly soften gluten structures; capping the inclusion at a precise 4 grams guarantees a stellar color and flavor profile without weakening your oven spring.
Perfecting Inclusions via Lamination: Rather than attempting to force heavy, slippery pumpkin seeds into the dough during the initial autolyse or mixing stages—which would physically slice through fragile gluten networks—this recipe relies on a clean lamination step. Stretching the relaxed dough into a thin sheet at 10:00 AM creates an orderly distribution of seeds, neatly layering them into the bread without compromising its structural volume.
