Sourdough Starter Discard Recipes | The Perfect Loaf (2024)

FAQs

How much of my starter should I use for a sourdough loaf? ›

As with any sourdough recipe, before you start baking bread, you want to make sure that your sourdough starter is as strong as possible. My basic sourdough recipe uses just 50g of starter for 500g of flour (so just 10% of starter).

The discard is not active enough to make sourdough bread rise but it does have many other uses and baking powder can be added if required. Savoury options include English breakfast muffins, pretzels, caramelised onion biscuits, and sourdough pizza dough.

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.

Don't throw it away! Instead, use it to make delicious and nutritious treats like pancakes, waffles, muffins, and bread. Sourdough discard is a great source of natural yeast and flavor, and can add a unique tangy taste to your baked goods.

Typical feeding ratios are 1:2:2 or 1:3:3 (old sourdough: fresh flour: water). However, even extreme ratios like 1:50:50 would still work. In that case, the freshly fed sourdough would just require more or much more time to grow and reach its peak, as judged by the maximum volume increase in the jar (at least doubled).

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.

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.

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.

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.

It adds a delicious flavor and imparts moisture to recipes which keeps bakes tasting fresher for much longer. You can also use sourdough discard to ferment recipes which makes them healthier and easier to digest.

Should sourdough discard be at room temperature before using? ›

When you're ready to use it, let the discard come to room temperature before using it to bake. I will keep sourdough discard in the fridge for about one week. I do know others that keep it much longer. The longer you keep it, the higher the risk of the discard growing mold or bad bacteria.

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.

No, it's not advisable to eat raw sourdough starter. While some people claim to have healed their gut problems by eating probiotic rich sourdough starter, it's not really advisable. Raw sourdough starter contains uncooked flour which can harbor harmful bacteria among other things.

Sourdough discard can also be used to start a new sourdough starter. You can gift the discard to a friend looking to start their own sourdough journey; all they need to do is feed it with water and flour to have a thriving starter of their own.

There is no single best ratio, but I've found a ratio of 1:5:5 fed twice daily at 12-hour intervals to produce a sourdough starter that's strong and healthy. This ratio corresponds to 20% ripe starter carryover, 100% water, and 100% flour (a mix of whole grain rye and white flour) at each feeding.

If you have too much starter compared to the additional flour and water you're adding, your hungry starter consumes all the nutrients and then it's not as bubbly.

A 1:2:2 feeding ratio would consist of one part existing starter, two parts flour and two parts water. For example, if you have 30g of existing starter, you would feed it 60g of flour and 60g of flour. The most common feeding ratios for daily maintenance are 1:1:1 or 1:2:2.

Now, sometimes, and it happens to the best of us, a sourdough starter can “get sick.” Overfeeding can be a cause of this “sickness,” as can lack of feeding and neglect. Because, yes, you can overfeed your sourdough.
