Step-by-Step Instructions
- Preheat oven to 350°F (175°C). Grease a loaf pan.
- Mix wet ingredients: Whisk together sourdough discard, applesauce, melted butter, sugar, eggs, lemon zest, lemon juice, and lemon extract until smooth.
- Prepare dry ingredients: In a separate bowl, whisk together flour, baking powder, and salt.
- Combine gently: Fold dry ingredients into wet, stirring until just mixed. (Overmixing = dense loaf!)
- Bake: Pour batter into the prepared pan and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
- Lemon syrup (optional): While warm, brush with a simple syrup made from 2 tbsp lemon juice + 2 tbsp sugar.
- Cool completely and glaze: Once cooled, drizzle with a lemon glaze for extra sweetness.

Expert Tips for a Perfect Loaf
- Use an active sourdough starter – it should be bubbly and fresh for the best results.
- Don’t overmix – stirring too much can make the loaf dense instead of tender.
- Test doneness with a toothpick – a clean toothpick ensures it’s fully baked.
- Experiment with flavors – swap out lemon for orange or lime for a fun twist.
- Let it cool before slicing – this helps the loaf hold its shape instead of crumbling.
