Sourdough Discard 101 (2024)

FAQs

How soon can you start using sourdough discard? ›

Remember, you can't use the discard from your homemade sourdough starter for the first 7 days. You can use sourdough discard in all kinds of sourdough discard recipes, including these no wait sourdough recipes, overnight sourdough discard recipes and sourdough discard recipes that use up a lot of discard.

You can always use this discard by directly mixing it into a dough for baking. Your discard, as long as it's in good shape, will leaven any bread dough just as well. The discard is just like a levain you would make for a recipe. The only difference is it's the same makeup as your starter.

The longer the discard sits in your refrigerator, the more fermented and “sour” it gets. I don't like to use discard that is more than one week old in discard recipes . After about a week, the discard can become very sour and impact the flavor of the discard recipe.

As long as it's not growing mold or bad bacteria, it's safe to use. It won't give you any rise, but it will add flavor! Remember: Sourdough starter and sourdough discard are pretty resilient!

If you don't get rid of the excess, eventually you'll have more starter than your feedings can sustain. After a few days, your daily 1/4 cup flour and water won't be enough to sustain your entire jar of starter, and your starter will be slow and sluggish, not much better than discard itself.

If your recipe calls for more than 227g (about 1 cup) of starter, feed it without discarding until you've reached the amount you need (plus 113g to keep and feed again).

Room temperature sourdough discard should be used, refrigerated, or thrown away after 36-48 hours. Sourdough discard can be kept in the fridge for weeks, BUT it continues to get sourer as time passes.

Yes, there are actually several health benefits to using sourdough discard in your cooking and baking. Sourdough discard is rich in probiotics, which can help promote a healthy gut microbiome and improve digestion.

It's not a good idea to use a sourdough starter right after feeding. Ideally you should wait at least 2-4 hours. When you first feed a sourdough starter, it's at its weakest point. It has not had time to consume the sugars in the flour and is flat and inactive.

It may develop a grayish liquid on top called “hooch” which can be poured off before use or stirred in. If you stir it in, the flavor will become more sour. You can continue to add more discard to the jar just pour it in and give it a stir before placing it back in the fridge covered.

Why discard half of sourdough starter? ›

If you don't discard your sourdough starter, it will grow too big and be unmanageable. Not to mention you will go through an unmentionable amount of flour.

Absolutely! A jar of sourdough discard serves as an insurance policy against starter death. If you have some discard on hand, remove a spoonful of it and feed it fresh flour and water in a clean jar. You should have a bubbly starter ready to bake with after a couple of feedings, depending on the discard's condition.

When you are ready to bake, remove the discard from the fridge and let it come to room temperature. I recommend keeping sourdough discard for up to one week. If needed, mark the date on the container in your refrigerator. After one week, there is a higher chance of the discard growing bad bacteria or mold.

If you've just created your sourdough starter, wait until it's reliably rising and falling each day with signs of fermentation—some rise, bubbles, a progressive sour aroma—before storing discard in your cache.

One note: Don't start using your discard until your starter is really up and running. In other words, if you've just started your starter and it's not yet established, then you shouldn't save that discard. Wait until you have a healthy, active sourdough starter, then keep any discard from routine feedings.

When Is Your Sourdough Starter Ready To Bake With? Your sourdough starter will not be ready for at least 14 days from when you started it. You can try to bake with it before 14 days, but honestly, you'll be rewarded with better bread if you wait.

It's not a good idea to use a sourdough starter right after feeding. Ideally you should wait at least 2-4 hours. When you first feed a sourdough starter, it's at its weakest point. It has not had time to consume the sugars in the flour and is flat and inactive.

Cover with either a tea towel or a glass lid. I like using a glass lid, because a towel tends to get really messy. Allow to sit of for 4-12 hours before using in a recipe, once it has about doubled in volume. If not using for baking, feed about 12-24 hours after last feeding or place in the fridge.
