Preheat and Prepare: Preheat your oven to 350 degrees Fahrenheit. Grease a standard loaf pan (9 x 5 inches) and set aside for later use.
Combine Wet Ingredients: In a large mixing bowl, whisk together sourdough starter, olive oil, lemon juice, lemon zest, eggs, and lemon extract until well blended.
Incorporate Dry Ingredients: Gradually add flour, sugar, baking soda, and salt to the wet mixture, stirring until smooth and evenly combined.
Bake to Perfection: Transfer the batter into the prepared loaf pan, spreading it out evenly. Bake in the preheated oven for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean.
Prepare the Glaze: In a medium bowl, whisk together fresh lemon juice and confectioner's sugar until smooth. Once the loaf has cooled slightly, drizzle the glaze over the top.
Serve and Enjoy: Slice the lemon bread and serve it as a delightful dessert or snack, savoring each citrus-infused bite.
