Crafting a delicious loaf of sourdough bread at home is a rewarding experience, and using quality ingredients like King Arthur Bread Flour can elevate your results. This stone-ground, high-gluten flour is particularly well-suited for sourdough, offering a rich, yeasty flavor and sturdy structure. In this guide, we'll walk you through a comprehensive sourdough bread recipe using King Arthur Bread Flour, step by step.
Before we dive into the recipe, let's ensure you have a vibrant sourdough starter. Maintaining a healthy starter is key to beautiful, airy sourdough loaves. If you haven't already, create a sourdough starter following these methods: the 100% hydration starter by Baking with Steel or the discard method by King Arthur Baking Company. Once your starter is active and bubbly, you're ready to begin.
Creating the Sourdough Levain
The first step in making sourdough bread is creating a levain, a pre-ferment that builds flavor and strengthens the dough. While you can use store-bought sourdough starter, making a levain from your own starter ensures optimal results.
The basic levain recipe is simple: equal parts by weight of active sourdough starter, water, and King Arthur Bread Flour. So, if your starter weighs 50g, you'll need 50g of water and 50g of flour. Combine these ingredients in a non-reactive container, cover it with a breathable lid or plastic wrap, and let it ferment at room temperature for about 4 hours, or until it has doubled in size and passes the float test.
Understanding Fermentation Times
Fermentation times can vary greatly depending on your kitchen's temperature and humidity, as well as the health of your starter and levain. In the summer, fermentation may happen quickly, while in the winter, it can take significantly longer. Room temperature typically ranges between 65-75°F (18-24°C) for optimal sourdough fermentation.
If your kitchen is cooler, you may need to adjust the fermentation times accordingly. For instance, a 12-hour bulk fermentation at 65°F (18°C) may require up to 18 hours in a kitchen that's only 60°F (15°C). Patience and observation are crucial in crafting the perfect sourdough loaf.
Feeding Your Sourdough Starter
Regular feedings maintain a healthy sourdough starter and ensure it's ready to levain your bread. Feed your starter at least once a day, using equal parts by weight of flour and non-chlorinated water. Discard a portion of the starter before feeding to keep its consistency manageable.
King Arthur Baking Company recommends a 100% hydration starter feed made primarily with King Arthur Bread Flour. This method maintains a highly functioning starter while fostering a rich, complex flavor in your sourdough bread.
Mixing the Dough
Once your levain is active and bubbly, it's time to mix the sourdough dough. In a large bowl, combine by weight: 400g of King Arthur Bread Flour, 320g of cool water (around 60°F or 15°C), and all of your levain. Mix until the ingredients form a rough, shaggy dough. This is your initial autolyse, which helps strengthen the gluten without kneading.
Let the dough rest for 30-60 minutes before performing a series of stretch and folds. With wet hands, gently pull and stretch the dough from one side and fold it over to the middle. Do this on all four sides, working your way around the bowl. You're not kneading the dough; instead, you're gently coaxing it into a more cohesive mass.
Understanding Stretch and Folds
Stretch and folds help build gluten structure and distribute the levain throughout the dough. You'll perform several rounds of stretches and folds during the bulk fermentation stage. After the initial set, let the dough rest for 30 minutes, then perform another round. Repeat this process 2-3 times, or until the dough feels more cohesive and slightly stronger.
The stretch and fold method is gentle on the dough and the baker, making it an excellent choice for those new to sourdough baking. It also yields incredibly flavorful bread with a complex, open crumb structure.
Automatic Methods and Stand Mixers
While stretch and folds are the traditional method for developing gluten in sourdough, you can also use automatic methods like a stand mixer or a kneading machine to achieve a strong dough. If you opt for a stand mixer, combine the ingredients on low speed until the dough comes together, then knead on medium-low speed for 6-10 minutes.
Keep in mind that stand mixers can overheat the dough, so monitor the temperature and stop the mixer if it gets too warm. Automatic methods may not yield the same signature sour flavor as stretch and folds, but they can produce excellent sourdough bread with less manual effort.
Bulk Fermentation
After performing a few sets of stretch and folds, you'll complete the bulk fermentation stage. This lengthy process, lasting anywhere from 8 to 12 hours or more, allows the dough to rise and build flavor. Maintain a room temperature of around 65-75°F (18-24°C) for optimal fermentation.
During the bulk fermentation, perform a series of stretch and folds every 30-60 minutes for the first 2-3 hours. This helps distribute the yeast and encourages even rising. After the first few hours, you can reduce the stretch and folds to every 60-90 minutes, or even let the dough rest undisturbed. Keep an eye on your dough, and watch for signs of increased volume, bubbles, and a slightly more airy texture when deflated.
The Poke Test
To determine if your dough is ready for shaping, perform the poke test. Gently poke the dough with a clean finger. If the indentation springs back slowly and not all the way, your dough is ready for shaping. If the indentation disappears immediately, the dough needs more fermentation time. Be careful not to under-or over-ferment your dough, as both can negatively impact the final loaf.
Cooling the Dough
After bulk fermentation, you'll need to cool the dough before shaping and cold fermentation. This helps prevent overproofing and creates better oven spring. Transfer the dough to a clean, lightly floured surface or bowl and wrap it tightly in plastic wrap. Place it in the refrigerator and let it cool for at least 1 hour, or up to 24 hours.
Cold fermentation not only improves the bread's final structure and flavor but also makes it easier to shape. The cold dough is more stable and less prone to sticking or tearing during the shaping process.
Shaping and Cold Fermentation
Once your dough is cooled, it's time to shape your loaf. Begin by dividing the dough into your desired weights, based on the bread's size and shape you want to achieve. For a boule (round loaf), divide the dough into approximately 500g pieces. For a batard (oval loaf), divide it into about 750g pieces.
Gently shape the dough using a bench scraper or your hands, taking care not to deflate it too much. To create a boule, gently pull the edges of the dough towards the center, pinching them together, and tucking them underneath to create a smooth, taut surface. For a batard, follow a similar process but shape the dough into an oval or rectangle instead of a ball.
Benching and Cold Fermentation
After shaping, place your loaf on a floured banneton (proofing basket) or a parchment-lined plate. Cover it loosely with plastic wrap and let it rest in the refrigerator for at least 3 hours, or up to 24 hours. This cold fermentation stage develops even more flavor and improves the loaf's structure and texture.
Before baking, allow your loaf to warm up at room temperature for about 1.5 to 2 hours. This encourages even rising and ensures the best possible oven spring. As the dough warms, preheat your oven and Dutch oven to high temperature (around 500°F or 260°C).
Scoring and Baking
Before baking, score your loaf with a lame, sharp knife, or scissors. Scoring allows steam to escape during baking, creating beautiful patterns and helping the loaf expand evenly. A simple crosshatch pattern works well for boules, while a single slit down the center is suitable for batards.
Transfer your scored loaf to the preheated Dutch oven, placing it seam side down if necessary. Put on oven mitts and carefully lower the Dutch oven onto a baking sheet or parchment paper, then slide both onto the oven rack. Bake covered for 20-30 minutes, then remove the lid and continue baking for another 20-30 minutes, or until the bread reaches an internal temperature of 205-210°F (96-99°C).
The combination of King Arthur Bread Flour's high gluten content and the sourdough fermentation process results in a beautiful, golden crust and a soft, open crumb. Your homemade sourdough bread will have a complex, tangy flavor and a texture that's worth every step in the process.
As you continue your sourdough journey, experiment with different hydration levels, fermentation times, and ingredient ratios. Bake with variations like whole wheat, rye, or sourdough discard, and perfect your technique over time. With practice, you'll become an adept sourdough baker, creating delicious, artisanal loaves that will impress family and friends. Happy baking!
