When you need to use a lot of starter but you don't have a lot of time, try this savory sourdough discard quick bread. It comes together in just over an hour.
In a medium mixing bowl, whisk dry ingredients together: flour, sugar, baking powder, baking soda, and salt.
In a smaller bowl, stir to combine wet ingredients: sourdough starter, butter, milk, and egg.
Pour the wet ingredients into the dry. Stir until well incorporated but do not over mix.
Spoon batter into a 9-inch by 5-inch baking pan lightly greased and lined with parchment paper.
Bake for 1 hour. Internal temperature should read between 195° and 200° Fahrenheit (90° and 93° Celsius).
Transfer to a wire cooling rack and let cool for 10 minutes before slicing and serving warm.
Notes
I keep my sourdough starter at 100% hydration, which means I feed it equal parts water and flour by weight rather than by volume. If your starter is fed at a different hydration, you may have to adjust the recipe to achieve the consistency you want. This is a quick bread, so please do not overmix the batter. Your loaf might sink in the middle if you do.
