Ingredients

• Active Sourdough Starter: 100 grams (fed and bubbly, ideally 4-8 hours before mixing)
• Warm Water: 350 grams (around 80-85°F / 27-29°C)
• Bread Flour: 500 grams (high protein content is best for structure)
• Salt: 10 grams (fine sea salt or kosher salt)

Instructions

1. Autolyse (Optional but Recommended): In a large mixing bowl, combine the 500 grams of bread flour and 350 grams of warm water. Mix with your hands or a spatula until just combined and no dry pockets of flour remain. The dough will be shaggy and sticky. Cover the bowl with a damp kitchen towel or plastic wrap and let it rest for 30 minutes to 1 hour. This resting period allows the flour to fully hydrate and gluten development to begin, making the dough more extensible and easier to work with.
2. Add Starter and Salt: After the autolyse, add the 100 grams of active sourdough starter and 10 grams of salt to the bowl. Mix everything together thoroughly. This can be done by hand using a pinching and folding motion, or you can use a stand mixer with a dough hook on low speed. Continue mixing until the starter and salt are fully incorporated into the dough and the mixture starts to come together. The dough will feel wet and sticky at this stage.
3. Bulk Fermentation (First Rise): This is where the magic of sourdough truly happens. Cover the bowl and let the dough rest at room temperature (ideally 75-78°F / 24-26°C) for 4 to 6 hours, or until the dough has increased in volume by about 50-75% and shows signs of fermentation, such as small bubbles on the surface. During this time, you will perform a series of ‘stretch and folds’ to build dough strength.
   • Stretch and Folds: Perform stretch and folds every 30-60 minutes for the first 2 to 3 hours of bulk fermentation. To do this, wet your hands slightly. Reach into the bowl, grab a portion of the dough, stretch it upwards gently, and fold it back over itself towards the center. Rotate the bowl and repeat this 3-4 times until all sides have been stretched and folded. This process gently develops gluten without overworking the dough.
4. Pre-Shaping: Once bulk fermentation is complete, gently turn the dough out onto a lightly floured work surface. Be careful not to degas the dough too much. Gently shape the dough into a round (boule) by pulling the edges towards the center and then flipping it seam-side down. Let the dough rest uncovered for 20-30 minutes. This resting period allows the gluten to relax, making the final shaping easier.
5. Final Shaping: Lightly flour your hands and the top of the dough. Gently flip the dough over so the smooth side is down. Shape the dough into a tight boule. There are many ways to do this, but a common method is to gently stretch the top edge down and seal it, then repeat with the sides. Imagine creating tension on the surface of the dough. The goal is to create a smooth, taut surface.
6. Cold Fermentation (Retarding): Lightly flour a clean kitchen towel or use a well-floured banneton (proofing basket). Carefully place the shaped dough, seam-side up, into the banneton or onto the floured towel. Cover the banneton or the towel with plastic wrap or a reusable shower cap. Place the banneton in the refrigerator for 12 to 24 hours. This cold fermentation slows down the yeast activity, allowing the LAB (lactic acid bacteria) to work their magic, developing more complex flavors and making the dough easier to score.
7. Preheat Oven and Dutch Oven: About 45 minutes to 1 hour before you plan to bake, place a Dutch oven (with its lid) into your oven and preheat to 475°F (245°C). It’s crucial that the Dutch oven is fully preheated to achieve that perfect oven spring and crust.
8. Score the Dough: Once the oven and Dutch oven are thoroughly preheated, carefully remove the Dutch oven from the oven. Take your dough out of the refrigerator. Gently invert the banneton or fold the towel so the dough releases onto a piece of parchment paper. Using a sharp razor blade (a lame or a clean, sharp knife works too), score the top of the dough. A simple cross or a single deep score often works well for a boule. This allows the steam to escape in a controlled manner, preventing blowouts and promoting good oven spring.
9. Bake: Carefully lift the parchment paper with the scored dough and lower it into the preheated Dutch oven. Place the lid back on the Dutch oven. Transfer the Dutch oven back into the oven.
10. Baking (Covered): Bake with the lid on for 25 minutes. This traps the steam released by the dough, which is essential for achieving maximum oven spring and a thin, crisp crust.
11. Baking (Uncovered): After 25 minutes, carefully remove the lid from the Dutch oven. Reduce the oven temperature to 450°F (230°C). Continue to bake for another 20-25 minutes, or until the crust is a deep golden brown and the internal temperature of the bread reaches at least 205°F (96°C).
12. Cooling: Once baked, carefully remove the bread from the Dutch oven and place it on a wire rack to cool completely. This is perhaps the hardest part, but it’s crucial! Cooling allows the interior of the bread to set and develop its final texture and flavor. Slicing into a hot sourdough loaf can result in a gummy texture. Aim for at least 2-3 hours of cooling.

Pro Tips for Sourdough Success

Achieving a truly beautiful sourdough boule is a journey of practice and observation. Here are some tried-and-true tips to elevate your bakes:

• Understand Your Starter: The health and activity of your sourdough starter are paramount. A ‘fed and bubbly’ starter means it has been recently fed and has doubled or tripled in size, with plenty of active bubbles. If your starter is sluggish, you might need to ‘revive’ it by feeding it more frequently for a few days before using it in your recipe.
• Flour Matters: The type of flour you use can significantly impact your sourdough. Bread flour, with its higher protein content, provides the necessary gluten structure for a good rise and chewy texture. While you can experiment with different flours, starting with a good quality bread flour will set you up for success.
• Temperature Control: Sourdough is sensitive to temperature. Warmer environments will speed up fermentation, while cooler ones will slow it down. Aim for a consistent room temperature, ideally between 75-78°F (24-26°C), during bulk fermentation for optimal results. If your kitchen is cold, you can create a warmer environment by placing your dough in a slightly turned-off oven with the light on.
• The Windowpane Test: This is a simple way to check gluten development. After a few stretch and folds, take a small piece of dough and gently stretch it between your fingers. If you can stretch it thin enough to see light through it without tearing, your gluten is well-developed. If it tears easily, it needs more stretching and folding.
• Gentle Handling: Sourdough dough is alive and delicate. Avoid overworking or degassing it unnecessarily. When shaping, be gentle and try to maintain as much of the air bubbles created during fermentation as possible.
• Proofing in a Banneton: A banneton (proofing basket) helps the dough hold its shape during the final rise and imparts beautiful, spiral-like patterns onto the crust. Ensure it’s well-floured to prevent sticking. If you don’t have one, a bowl lined with a well-floured tea towel will work.
• The Importance of the Dutch Oven: Baking in a preheated Dutch oven is key to achieving a superior crust and maximum oven spring. The trapped steam allows the dough to expand fully before the crust begins to set.
• Don’t Rush the Cool Down: Resist the temptation to cut into your loaf as soon as it comes out of the oven. The internal structure needs time to set. Allowing it to cool completely on a wire rack will prevent a gummy interior and allow the flavors to fully develop.

Chef’s Secret Tip

For an exceptionally crispier crust and to ensure your loaf slides out of the Dutch oven without sticking, dust the bottom of your Dutch oven with a tablespoon of cornmeal or semolina flour before placing the parchment paper with your dough into it. This creates a delightful texture and adds an extra layer of protection against sticking.

Frequently Asked Questions (FAQs)

My sourdough starter isn’t very active. What can I do?

A sluggish starter might need some attention. Try feeding it twice a day for 2-3 days with equal parts flour and water. Discard most of the starter before each feeding to encourage fresh growth. Ensure it’s in a warm environment (around 75-78°F / 24-26°C).

My dough feels too sticky. Is that normal?

Sourdough dough is often wetter and stickier than commercial yeast dough, especially in the beginning. The autolyse and stretch and folds will build strength. If it’s unmanageable, you might be using too much water or your flour might be less absorbent. Lightly flouring your hands and your work surface can help. In hot weather, you might need slightly less water.

How do I know when bulk fermentation is done?

Look for visual cues. The dough should have increased in volume by 50-75%, feel airy and jiggly, and you might see small bubbles on the surface and along the sides of the bowl. It should also feel more alive and less dense than when you started.

What is ‘scoring’ and why is it important?

Scoring is making cuts on the surface of the dough before baking. It’s important because it controls where the bread expands during baking (oven spring). Without scoring, the dough can burst open in unpredictable places. It also adds to the aesthetic appeal of the loaf.

My bread didn’t rise much in the oven. What went wrong?

This could be due to several factors: an under-developed starter, insufficient bulk fermentation, over-proofing (allowing the dough to rise too much before baking), or an oven that isn’t hot enough. Ensure your starter is vigorous, your bulk fermentation is adequate but not excessive, and your oven and Dutch oven are fully preheated.

Can I bake sourdough without a Dutch oven?

Yes, you can! While a Dutch oven is ideal for trapping steam, you can achieve good results by placing a baking stone or steel in your oven and creating steam. You can do this by placing a metal pan (like a cast-iron skillet or a broiler pan) on the rack below your baking stone/steel. When you put your bread in, pour about a cup of hot water into the preheated pan to create steam. Be cautious of the steam when opening the oven door.

How long can I store my sourdough bread?

Sourdough bread generally stays fresh longer than regular bread due to its acidity. At room temperature, it will be best for 2-3 days when stored in a paper bag or bread box. For longer storage, slice the cooled bread and freeze it in airtight containers or freezer bags. It can be frozen for up to 3 months.
