This easy sourdough starter recipe uses just whole wheat flour, all-purpose flour, and water. It’s perfect for beginners and comes together in just 5 days!
Day 1: Mix - In your jar, mix ½ cup whole wheat flour, ½ cup all-purpose flour, and 1 cup water. Stir until smooth. Scrape down the sides. Cover loosely and let it sit at room temperature for 24 hours.
Day 2: Check & Feed - You might see a few bubbles—great! Discard about half the mixture (just eyeball it). Add: ¼ cup whole wheat flour, ¼ cup all-purpose flour, and ½ cup water. Mix well.
Day 3–5: Feed Daily - Repeat the same feeding: discard half, then feed with the flour mix and water. By Day 4 or 5, it should be doubling in size within 4–8 hours and smell slightly tangy, yeasty, and pleasant.
Day 6+: Ready to Use - Once your starter is consistently rising and falling with bubbles and a sweet-sour smell, it's ready to bake! You can now store it in the fridge and feed it 1–2 times per week.
