Ingredients

• Active Sourdough Starter: 100 grams (fed and bubbly, at room temperature)
• Warm Water: 350 grams (around 80-85°F / 27-29°C)
• Bread Flour: 500 grams (high protein content, typically 12-14%)
• Fine Sea Salt: 10 grams

Instructions

1. Autolyse (Mixing Flour and Water): 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 flour remains. It will look shaggy and sticky. Cover the bowl with a damp tea towel or plastic wrap and let it rest for 30 minutes to 1 hour. This process, called autolyse, allows the flour to hydrate, gluten development to begin naturally, and makes the dough more extensible and easier to handle later on.
2. Adding Starter and Salt: After the autolyse period, add the 100 grams of active sourdough starter and 10 grams of fine sea salt to the dough. Wet your hands slightly to prevent sticking. Gently pinch and squeeze the starter and salt into the dough. Continue to mix and fold the dough within the bowl for about 5-7 minutes until the starter and salt are thoroughly incorporated. The dough will still feel sticky, but it should start to feel a bit smoother and more cohesive.
3. Bulk Fermentation (First Rise): Cover the bowl again and let the dough rest in a warm place (ideally 75-78°F / 24-26°C) for 4-6 hours. During this time, you will perform a series of “stretch and folds.” For the first 2 hours, perform a set of stretch and folds every 30 minutes. To do this: wet your hands, reach under one side of the dough, gently pull it upwards, and fold it over the center. Rotate the bowl 90 degrees and repeat three more times, completing four folds in total for each set. After the first 2 hours (which will involve 4 sets of stretch and folds), let the dough rest undisturbed for another 2-4 hours, or until it has increased in volume by about 50-75% and looks puffy and slightly domed. You should see some small bubbles on the surface.
4. Pre-Shaping: Lightly flour a clean work surface. Gently tip the dough out of the bowl onto the floured surface. Be careful not to deflate it too much. Using a bench scraper or your hands, gently coax the dough into a rough round shape. Let it rest, uncovered, for 20-30 minutes. This allows the gluten to relax, making the final shaping easier.
5. Final Shaping: Lightly flour the top of your rested dough. Flip the dough over so the floured side is now down. Gently shape the dough into your desired boule (round loaf) shape. For a boule, you want to create surface tension. Imagine tucking the edges of the dough underneath itself, creating a taut skin on the top. Be firm but gentle.
6. Second Fermentation (Proofing): Prepare a banneton (proofing basket) or a bowl by lining it with a well-floured tea towel (use rice flour or a mix of rice and all-purpose flour to prevent sticking). Carefully place the shaped dough seam-side up into the prepared banneton. Cover the banneton with plastic wrap or a damp tea towel. Place it in the refrigerator for 12-24 hours. This long, cold proof develops flavor and makes the dough easier to score.
7. Preheat Oven and Dutch Oven: About 45 minutes before you plan to bake, preheat your oven to 475°F (245°C). Place a Dutch oven (with its lid) inside the oven to preheat as well. A Dutch oven is crucial for trapping steam, which helps achieve that amazing oven spring and crispy crust.
8. Scoring the Dough: Once the oven and Dutch oven are fully preheated, carefully remove the Dutch oven from the oven. Take your dough out of the refrigerator. Gently invert the banneton onto a piece of parchment paper. The dough should slide out easily. Using a sharp razor blade (a lame or sharp knife), quickly and confidently score the top of the dough. A common pattern is a single deep slash or a cross shape. This allows the dough to expand predictably in the oven.
9. Baking (Covered): Carefully lift the parchment paper with the scored dough and gently lower it into the hot Dutch oven. Place the lid back on the Dutch oven. Carefully place the Dutch oven back into the preheated oven. Bake for 25 minutes with the lid on.
10. Baking (Uncovered): After 25 minutes, carefully remove the lid of the Dutch oven. The bread should have puffed up and started to brown. Continue to bake for another 20-30 minutes, or until the crust is a deep golden brown and the internal temperature of the loaf reaches 205-210°F (96-99°C) when measured with an instant-read thermometer.
11. Cooling: Carefully remove the bread from the Dutch oven and place it on a wire rack to cool completely. This is perhaps the hardest part – resisting the urge to slice into it while it’s still hot! Cooling allows the internal structure of the bread to set and the flavors to fully develop. Slicing too early can result in a gummy texture.

Chef’s Secret Tip

For an extra glossy crust, after you remove the lid of the Dutch oven for the final bake, you can lightly spritz the top of the loaf with water using a spray bottle. This encourages a more delicate and crackly crust. Be quick to close the oven door to retain heat!

Pro Tips for Sourdough Success

Mastering sourdough is a rewarding process, and a few key tips can make all the difference. Don’t be discouraged if your first loaf isn’t perfect; each bake is a learning experience. Pay attention to your starter’s activity. A robust, bubbly starter is the foundation of a good loaf. If your starter seems sluggish, try feeding it more frequently or adjusting the hydration. The temperature of your kitchen significantly impacts fermentation times. If your home is cooler, your dough will take longer to rise. Conversely, a warmer environment will speed things up. Learning to “read” your dough – its texture, its rise, its signs of fermentation – is more important than sticking rigidly to timings.

When it comes to flour, using a good quality bread flour with a high protein content is crucial for developing strong gluten, which gives your loaf structure and chew. While you can certainly experiment with whole wheat or rye flours, start with a 100% bread flour loaf to get a feel for the process. Don’t be afraid of a sticky dough; this is often a sign of good hydration, which contributes to an open crumb. Using a bench scraper and lightly floured hands will help you manage it effectively. The cold proof in the refrigerator is not just for convenience; it’s a vital step for flavor development. The slow fermentation allows complex flavors to emerge and also makes the dough firmer and easier to score.

When scoring, a sharp blade is your best friend. A dull blade will drag and tear the dough, hindering its ability to spring upwards. Practice makes perfect, so don’t worry about making beautiful patterns initially; focus on a clean, decisive cut that allows the bread to expand. The Dutch oven is a game-changer for home bakers. If you don’t have one, you can try using a baking stone with a cast-iron skillet filled with lava rocks or water placed on the bottom rack to create steam. However, a Dutch oven is highly recommended for consistent results. Finally, patience during the cooling phase is paramount. Resist the urge to cut into that warm, steamy loaf. Allowing it to cool completely will result in a superior texture and flavor.

Frequently Asked Questions

How do I know if my sourdough starter is active enough?

An active sourdough starter will be bubbly, airy, and will have doubled in volume within 4-8 hours after being fed. When you drop a small spoonful into a glass of water, it should float. If it sinks, it needs more time to become active.

Can I use all-purpose flour instead of bread flour?

While you can technically make sourdough with all-purpose flour, it’s not ideal. Bread flour has a higher protein content, which is essential for developing the strong gluten network needed for a good sourdough structure and chewy texture. Using all-purpose flour may result in a denser loaf with a less open crumb.

My dough is too sticky. What can I do?

A sticky dough is common in sourdough, especially with higher hydration recipes. Resist the urge to add too much extra flour during the initial stages, as this can make the bread dense. Instead, keep your hands slightly damp when handling the dough, and use a bench scraper. As the gluten develops through stretching and folding, the dough will become more manageable.

How can I tell if my bulk fermentation is finished?

Look for visual cues. The dough should have increased in volume by about 50-75% (not necessarily doubled). It should look puffy and airy, with a domed surface and some small bubbles visible. You can also do a “windowpane test”: gently stretch a small piece of dough. If you can stretch it thin enough to see light through it without tearing, the gluten is well-developed.

What if I don’t have a banneton?

You can easily substitute a banneton with a bowl lined with a clean tea towel. Make sure the towel is well-floured (using rice flour or a mix of rice and all-purpose flour) to prevent the dough from sticking. The key is to provide support and a slightly floured surface for the final proof.

Why is my sourdough crust not crispy?

A crispy crust is usually achieved through proper steam during the initial baking phase and sufficient heat. Ensure you’re preheating your Dutch oven thoroughly, baking with the lid on for the first 20-25 minutes to trap steam, and then removing the lid to allow the crust to brown and crisp up. Make sure to let the loaf cool completely on a wire rack to prevent the bottom crust from becoming soggy.
