Recipe Tips
Use Fresh Lemon Zest & Juice: Fresh lemons provide the best flavor, as bottled juice lacks the bright citrusy notes. To maximize juice, roll the lemon on the counter before cutting. Always zest before juicing, using a fine grater to avoid the bitter white pith. For extra flavor, rub the zest into the sugar before mixing to release its oils.
Let the Loaf Rest Overnight for Better Flavor: The lemon flavor deepens and the texture improves if the loaf rests overnight. Once cooled, wrap it in parchment or plastic wrap and store at room temperature. For extra moisture, brush with lemon syrup before wrapping.
Optinal Lemon Glaze for Extra Sweetness: For a glossy finish and added moisture, drizzle with a simple glaze made from 60g powdered sugar and 15-30ml fresh lemon juice. Apply only after the loaf has fully cooled.
Ingredients You Need for a Lemon Sourdough Discard Loaf
- All-purpose flour provides the structure and stability of the loaf, forming the base of the batter and giving the bread its texture. It absorbs moisture and interacts with other ingredients to create a tender crumb.
- Baking powder acts as a leavening agent, helping the loaf rise by creating air pockets when combined with liquid and heat. It ensures a light and fluffy texture.
- Salt enhances the overall flavor by balancing the sweetness and bringing out the bright citrus notes of the lemon. It also helps strengthen the gluten structure.
- Granulated sugar sweetens the loaf and contributes to its moist, tender texture. It also helps with browning, creating a golden crust as it caramelizes during baking.
- Lemon zest intensifies the citrus aroma and flavor by releasing its natural essential oils into the batter. It enhances the lemony taste more than juice alone.
- Eggs provide structure, richness, and stability. They help emulsify the ingredients, ensuring a smooth batter, and contribute to a soft, tender crumb.
- Plain whole-milk yogurt adds moisture and slight tanginess, enhancing the flavor and tenderness of the loaf. Its acidity also helps activate the baking powder, contributing to the rise.
- Canola oil keeps the loaf moist and tender by adding fat without making it too heavy. Unlike butter, oil remains liquid at room temperature, resulting in a softer texture.
- Lemon juice provides acidity, which enhances the tangy flavor and reacts with the baking powder to improve the loaf’s rise. It also keeps the loaf fresh by slowing oxidation.
- Sourdough discard adds complexity to the flavor with a subtle tang and enhances the loaf’s moisture. Its acidity also interacts with the leavening agents to create a lighter texture.
Directions – How to Make Lemon Sourdough Discard Loaf
Preheat & Prep: Heat oven to 175ºC (350ºF). Grease a 22x11cm (8,5×4,5-inch) loaf pan and line it with parchment paper, leaving a 2,5 cm (1-inch) overhang on the long sides. Infuse Sugar: In the bowl of a stand mixer fitted with the paddle attachment, mix the lemon zest and sugar on low speed until fragrant.
Mix Wet Ingredients: Whisk in eggs, yogurt, and oil on medium speed, until smooth (about 2 minutes). Then, whisk in the sourdough starter and lemon juice on medium speed, until combined (about 1 minute). Scrape down the bottom and the sides of the bowl with a silicone spatula.
Combine Dry Ingredients: In a small bowl, whisk together the flour, baking powder, and salt. Finish Batter: Whisk the dry ingredients into the wet mixture on low speed, until just combined (about 1 minute).
Bake: Pour batter into the prepared loaf pan and bake on the middle rack for 45–50 minutes, until golden and a toothpick inserted in the center comes out clean. Cool: Let the loaf cool in the pan for 10 minutes, then lift it out using the parchment overhang and transfer to a wire rack. Cool for at least 30 minutes before slicing.
Storing, Freezing & Thawing Instructions
Storage: Once the loaf has completely cooled, store it in an airtight container or wrap it tightly in plastic to prevent it from drying out. It will stay fresh at room temperature for up to 3 days. If you want to keep the loaf for more than 3 days, store it in the fridge. Wrap it tightly in plastic or place it in an airtight container. While refrigeration can slightly dry out baked goods, warming slices before serving helps restore their moisture. The loaf will keep in the fridge for up to 1 week.
Freezing Instructions: To freeze the entire loaf, first let it cool completely. Wrap it tightly in plastic, then add a layer of aluminum foil or place it in a ziplock bag. Store in the freezer for up to 3 months. For easy portioning, slice the loaf before freezing. Wrap each slice individually in plastic and place them in a ziplock bag or container. This allows you to take out just the amount you need without defrosting the whole loaf. Frozen slices are best enjoyed within 3 months.
Thawing: To thaw a whole loaf, remove it from the freezer and let it sit at room temperature, still wrapped, for a few hours until fully defrosted. You can also place the wrapped loaf in the fridge overnight. For individual slices, let them thaw at room temperature for 15–20 minutes. To restore freshness, warm a slice in the microwave for 10–15 seconds or lightly toast it for a crisp exterior.
My Summary for Lemon Sourdough Discard Loaf
Difficulty: Simple.
Taste: This loaf has a bright, tangy lemon flavor. The fresh lemon zest intensifies the citrus notes, while the sourdough discard adds a mild tang, giving the loaf a deeper, more nuanced taste compared to a traditional lemon cake. The sugar rounds out the tartness, creating a pleasant contrast without being overly sweet.
Texture: The texture is soft, moist, and tender, thanks to the combination of yogurt, oil, and sourdough discard, which help retain moisture. The crumb is slightly denser than a classic pound cake but still light and airy. The crust bakes to a golden brown, offering a slight crispness that contrasts beautifully with the soft interior.
