Ingredients

• 200 grams active, bubbly sourdough starter (fed 4-12 hours prior)
• 750 grams bread flour
• 150 grams whole wheat flour
• 650-700 grams lukewarm water (around 80-85°F or 27-29°C) – *start with 650g and add more if needed*
• 20 grams fine sea salt
• Rice flour or semolina for dusting

The quality of your ingredients makes a difference. Using good bread flour will provide the necessary gluten structure for a strong loaf. The whole wheat flour adds a lovely depth of flavor and contributes to a richer crumb. Your sourdough starter is the heart of this recipe. Make sure it’s active and vibrant – it should have doubled in size and be full of tiny bubbles. Lukewarm water is important for optimal yeast activity without killing it. Salt, of course, is essential for flavor and controlling fermentation. And a little rice flour or semolina helps prevent sticking when you’re transferring your dough.

Instructions

1. Autolyse: In a large mixing bowl, combine the bread flour, whole wheat flour, and 650 grams of the lukewarm water. Mix with your hands or a spatula until just combined. There should be no dry pockets of flour. Cover the bowl and let it rest for 30 minutes to 1 hour. This step, called autolyse, allows the flour to hydrate and gluten development to begin without any kneading.
2. Add Starter and Mix: After the autolyse, add the active sourdough starter to the dough. Dimple it into the dough with your fingers. Then, gradually add the remaining 50 grams of water if the dough feels too stiff. Mix until the starter is fully incorporated. The dough will be shaggy at this stage.
3. Add Salt and Mix: Sprinkle the salt over the dough. Mix it in thoroughly. This can be done by pinching and folding the dough within the bowl or using a dough whisk. The dough will start to feel a bit more cohesive.
4. Bulk Fermentation (First Rise): This is the most crucial stage for flavor and structure development. Cover the bowl and let the dough rest at room temperature. For the next 2-3 hours, perform a series of “stretch and folds” every 30 minutes. To do this, wet your hands slightly. Grab one side of the dough, stretch it upwards gently, and fold it over the center of the dough. Rotate the bowl and repeat this process with all four sides of the dough. After each set of folds, the dough should feel smoother and more elastic. You are building strength in the dough. After the initial 2-3 hours of folds, let the dough continue to ferment, covered, for another 4-8 hours (or until it has increased in volume by about 30-50% and shows signs of aeration, like bubbles on the surface). The exact time will depend heavily on your room temperature and starter activity.
5. Pre-shape: Gently turn the dough out onto a lightly floured surface. Using a bench scraper and lightly floured hands, gently coax the dough into a round shape. Be careful not to degas it too much. Let it rest, uncovered, for 20-30 minutes. This allows the gluten to relax.
6. Final Shape: Lightly flour the top of the dough. Flip it over so the floured side is down. Now, shape it into a taut ball (boule). You can do this by folding the edges into the center, then gently pulling the dough towards you on the counter to create surface tension. Alternatively, you can use the “stitch” method by gently pulling the dough across the surface, creating tension underneath. Be firm but gentle.
7. Cold Fermentation (Second Rise): Generously dust a proofing basket (banneton) or a bowl lined with a floured tea towel with rice flour or semolina. Carefully place the shaped dough seam-side up into the basket. Cover the basket with plastic wrap or a damp tea towel and refrigerate for 12-24 hours. This long, cold fermentation develops complex flavors and makes the dough easier to score and handle.
8. Preheat Oven: About 45-60 minutes before you plan to bake, preheat your oven to 475°F (245°C) with a Dutch oven (with its lid on) or a baking stone and a steam pan inside.
9. Score and Bake: Carefully remove the dough from the refrigerator. Gently invert the proofing basket onto a piece of parchment paper or directly into your preheated Dutch oven (be very careful, it’s hot!). Using a lame or a very sharp razor blade, score the top of the dough. A simple cross or a more decorative pattern works well. Aim for a confident, shallow cut.
10. Baking (with Dutch Oven): Carefully place the lid on the Dutch oven and place it in the oven. Bake for 20 minutes.
11. Baking (without Dutch Oven): If using a baking stone, slide the dough (on parchment paper) onto the stone. Pour about 1 cup of hot water into the steam pan below. Close the oven door quickly.
12. Continue Baking: After 20 minutes (or when the crust starts to set if not using a Dutch oven), carefully remove the lid from the Dutch oven. Reduce the oven temperature to 450°F (230°C). Continue to bake for another 25-30 minutes, or until the crust is a deep golden brown and the internal temperature of the bread reaches 205-210°F (96-99°C).
13. Cool: Once baked, carefully remove the bread from the oven and place it on a wire rack to cool completely. This is crucial! Resist the urge to slice into it too soon; the inside is still setting and releasing steam. Allowing it to cool fully ensures the best texture and flavor.

This step-by-step guide aims to demystify the sourdough process. The autolyse is a gentle introduction to hydration. Bulk fermentation is where the magic truly happens, with the stretch and folds building the dough’s structure. Cold fermentation is your secret weapon for flavor and ease of handling. Scoring is your artistic touch, and the baking process, especially with a Dutch oven, is key to achieving that coveted crust.

Chef’s Secret Tip: Don’t be afraid of a sticky dough. A slightly wetter dough (higher hydration) often leads to a more open crumb. If your dough feels too unmanageable during stretch and folds, wet your hands even more and work quickly. A well-developed gluten network, even in a sticky dough, will hold its structure.

Pro Tips for Sourdough Success

* Room Temperature is Key: The temperature of your kitchen significantly impacts fermentation times. Warmer rooms will speed things up, while cooler rooms will slow them down. Get to know your dough and look for visual cues (volume increase, bubbles) rather than strictly adhering to times.
* Starter Health is Paramount: A weak or sluggish starter will result in a dense, flat loaf. Ensure your starter is consistently active and bubbly before you begin. Feed it regularly and at the right ratio for your needs.
* Master the Stretch and Fold: These gentle folds build the gluten structure that gives sourdough its chew and open crumb. Don’t skip them, and don’t overwork the dough. Be consistent with your folding technique.
* The Art of Shaping: A well-shaped loaf will hold its form during baking and contribute to a beautiful final product. Practice creating surface tension without degassing the dough. It takes a little getting used to, but it’s a skill that greatly improves your results.
* Dutch Oven Magic: A Dutch oven traps steam, which is essential for sourdough. The steam keeps the crust soft initially, allowing the loaf to rise to its full potential (oven spring). Once you remove the lid, the heat is allowed to crisp and brown the crust.
* Don’t Rush the Cooling: This is perhaps the hardest part. Letting the bread cool completely on a wire rack allows the internal structure to set and the moisture to equalize. Slicing too early can result in a gummy texture. Patience will be rewarded.

Frequently Asked Questions (FAQs)

What is sourdough starter and how do I maintain it?

Sourdough starter is a fermented mixture of flour and water that contains wild yeast and bacteria. It’s your leavening agent for sourdough bread. To maintain it, you typically “feed” it with fresh flour and water daily or every few days, depending on how often you bake. A healthy starter should be bubbly, rise predictably after feeding, and have a pleasant, slightly tangy aroma.

My dough is too sticky, what should I do?

A little stickiness is normal, especially with higher hydration doughs. Try wetting your hands slightly when handling the dough during stretch and folds. Avoid adding too much extra flour during the process, as this can alter the hydration and texture of the final bread. If it’s extremely unmanageable, a brief rest in the bowl can help.

Why is my sourdough flat?

A flat sourdough loaf can be caused by several factors: a weak starter, under-proofed dough (not enough bulk fermentation), over-proofed dough (too much fermentation), or poor shaping. Ensure your starter is active, pay close attention to the visual cues during bulk fermentation, and practice your shaping technique to build good surface tension.

How do I get a good crust on my sourdough?

A good crust is achieved through proper baking conditions. Using a Dutch oven creates steam, which is vital for oven spring and a crackling crust. Baking at a high initial temperature and then reducing it is also key. Ensure the loaf is baked long enough to develop a deep golden-brown color.

Can I use all bread flour instead of a mix with whole wheat?

Yes, you can absolutely use all bread flour. Using a portion of whole wheat flour adds a subtle nutty flavor and a slightly denser, more robust crumb, which many people enjoy. If you prefer a lighter crumb and flavor, stick to just bread flour. You might need to adjust the water slightly as whole wheat flour can absorb more liquid.
