Transforming sourdough discard into a delightful focaccia bread might seem like an unlikely feat, but it's not only possible, but also yields a delicious result. Sourdough discard is the portion of your sourdough starter that you usually toss out when feeding it. However, with the right recipe and techniques, this "waste" can be repurposed into a beautiful, aromatic focaccia bread that's perfect for snacking, sandwiches, or alongside your favorite meals.
Focaccia, hailing from the Liguria region of Italy, is a flatbread with a crispy exterior and a soft, chewy interior. It's typically flavored with olive oil, salt, and sometimes herbs. By incorporating your sourdough discard into your focaccia dough, you're adding natural yeast, sourness, and a unique texture that sets your bread apart.
Understanding Sourdough Discard
Sourdough discard is the unfed portion of your sourdough starter. When you maintain a sourdough starter, you regularly "feed" it by discarding a portion and adding fresh flour and water. The discard, while not immediately usable for bread making, still contains active yeast and beneficial bacteria from the starter.
Using sourdough discard in your focaccia recipe not only reduces waste but also imbues your bread with a complex, tangy flavor and improves its keeping qualities. Moreover, it can make the dough more forgiving, as the active yeast and bacteria help with rising and fermentation.
Choosing the Right Discard-to-Flour Ratio
When using sourdough discard in your focaccia recipe, it's crucial to find the right balance between discard and fresh flour. Too much discard can weigh down the dough and make it dense, while too little might not provide enough sourness or yeast activity.
A good starting point is a 1:1 ratio of discard to fresh flour by weight. This ratio maintains a light, airy texture while imparting a pleasant tang. However, feel free to adjust this ratio according to your taste preferences and the specific characteristics of your sourdough starter.
Reviving Sourdough Discard
Before incorporating your discard into your focaccia dough, it's a good idea to revive it. This process reactivates the yeasts and bacteria, ensuring they're ready to work their leavening magic in your bread. To revive your discard, simply mix it with equal parts by weight of flour and water, and let it sit at room temperature for about an hour.
After an hour, you should see signs of activity, such as bubbles forming on the surface. If not, let it sit for a bit longer. Once your discard shows signs of life, it's ready to be incorporated into your focaccia dough.
Creating Your Sourdough Discard Focaccia
Now that you've prepped your sourdough discard, it's time to create your delicious focaccia. This recipe yields one large focaccia, perfect for sharing or meal prep. As with any bread-making process, patience is key, so make sure to account for ample rising time.
Before you get started, have your ingredients at room temperature for easier incorporation and more even rises:
- Revived sourdough discard (equal parts discard, flour, and water by weight)
- Fresh flour (e.g., all-purpose or bread flour)
- Warm water
- Extra virgin olive oil (plus more for drizzling)
- Salt
- Optional additives (e.g., herbs, garlic, or grated cheese) for toppings
Mixing the Dough
In a large bowl, combine your revived sourdough discard, fresh flour, and water. Mix until a shaggy dough forms. Cover the bowl with a clean, damp cloth and let it rest for 30 minutes. This step allows the flour to fully hydrate and the initial fermentation process to begin.
After 30 minutes, add salt to the dough and mix well to distribute. At this point, you can also incorporate any optional additives. Once the salt is fully mixed in, start adding olive oil to the dough, one tablespoon at a time. This process may take several minutes, but it's crucial for developing the focaccia's unique texture and flavor. Work the oil into the dough until it becomes silky and soft.
First Rise and Shaping
The dough should now be sticky and somewhat difficult to handle, but adjustable with a bench scraper. Let it rest, uncovered, for 30 minutes. After resting, turn the dough out onto a well-floured surface. Using a bench scraper or spatula, gently stretch and fold the dough over itself a few times to build structure. This process, called "stretch and fold," can be repeated several times at 30-minute intervals for enhanced gluten development and a lighter texture.
After a couple of stretch-and-fold sessions, let the dough rest for 60-90 minutes. Then, transfer it to a well-oiled baking sheet or focaccia pan. Using your fingers, press the dough evenly into the pan, dimpling the surface. Don't worry if the dough seems resistant at first – just be patient and let it relax. Once the dough covers the entire pan, cover it with a cloth and let it rise in a warm, draft-free place for about 2 hours. During this time, the dough should almost double in size.
Final Rise and Baking
Just before baking, preheat your oven to 450°F (230°C) with a baking stone or steel, if available. Before transferring the dough to the oven, lightly oil the surface of the focaccia, then sprinkle with coarse salt and any additional toppings. Using a sharp knife or lame, score the focaccia with diagonal cuts, creating a diamond pattern. This step helps steam escape during baking and gives the focaccia its signature appearance.
Carefully transfer the focaccia, still on the baking sheet, onto the preheated baking surface. Bake for 15-20 minutes, or until the top is golden-brown and the crust is crisp. For extra-crispy results, carefully flip the focaccia onto a wire rack and bake the other side for an additional 5-10 minutes. Allow the focaccia to cool completely before slicing and serving.
Transforming sourdough discard into irresistible focaccia bread is not only rewarding but also a fantastic way to reduce waste in the kitchen. The next time you feed your sourdough starter, remember that potential future focaccia waiting in the wings. Embrace the process, experiment with different toppings, and enjoy the satisfaction of creating something delicious from what was once considered "waste." Happy baking!
