Common Mistakes to Avoid
Making sourdough discard donuts can be a fun experience, but there are a few common mistakes to watch out for.
- Not using fresh sourdough discard: Ensure your sourdough discard is at room temperature and fed within the last 12 hours for the best results. Old or cold discard can lead to denser donuts.
- Over-kneading the dough: Kneading too much can make your donuts tough. Only knead until a smooth dough forms to keep them light and fluffy.
- Skipping the flour on the counter: Not flouring your surface can cause sticky dough, making it hard to roll out. Always sprinkle flour generously before working with the dough.
- Incorrect air fryer or oven temperature: Make sure to preheat your appliances properly. Cooking at the wrong temperature may result in unevenly cooked donuts.
- Waiting too long to enjoy: These donuts are best enjoyed fresh. Waiting too long can affect their texture and flavor, so serve them right away!
