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.

You can store mature sourdough discard in the refrigerator indefinitely. As long as there is no mold, it is good to use. 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.

Do I have to discard my sourdough starter? It would be best if you discarded some portion of your starter each time you feed it unless you want to continue to let it grow. Eventually, you need to discard the used “food” (flour and water) that's been used to sustain your starter during the last fermentation period.

You can use old sourdough discard if it's been stored in the fridge, however, you really want to use it up within a week - 2 weeks max.

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.

I left my sourdough discard out at room temperature for a few days. Is it okay? As long as your kitchen isn't too warm (I'd say 78°F or higher) your starter/discard will be fine stored at room temperature for at least a few days without feeding. The flavor will get more acidic the longer it sits.

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.

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.

Can you use an active starter in place of a discard? ›

Absolutely you can! Active starter can be used in the same way as sourdough discard in sweet or savory baking. You can add active sourdough starter to any recipe you would add discard to following the same calculation.

Can I use my sourdough discard straight out of the fridge to refresh my starter? Yes! You do not need to warm it up first. Just grab what you need and do your refreshing!

stir your starter in between feedings - try stirring it twice in between feedings and really give it a chance to get oxygen into the mix. This will help to activate your starter without too much effort.

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.

I recommend keeping sourdough discard for up to one week. After that point, there is a higher risk of bad bacteria or mold growing. How often should I feed my sourdough starter? I recommend feeding your starter at least once per week.

*Do not try baking with your starter right after feeding it. Allow time for it to grow and feast on the flour before using it. Starters are usually ready to bake with around 4-12 hours after a feeding depending on the amount you feed your starter. The larger the feeding, the more time it needs to ferment.

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.

Mature sourdough starter aged more than 6 months old should be able to survive unfed on the counter for around 3-4 days without any risk of mold. The caveat here is if the temperature is very hot, this timeframe would be reduced. A mature sourdough starter will survive unfed in the fridge for months.

Store it for future baking: You can store sourdough discard in an airtight container in the refrigerator for future baking with sourdough discard recipes. When you're ready to use it, let the discard come to room temperature before using it to bake.
