So, you’ve gotten into baking sourdough, huh? One of the original DIY projects, baking your own bread is a great way tocook sustainablyand produce your own food. Once an iconic homesteader’s activity, this age-old craft has become apopular hobbyrecently as many Americans are staying inside during the COVID-19 crisis, with some turning to stress baking to calm anxious nerves, while others aim to provide their own bread supply as grocery stores and online retailers run out. Both newbie bakers and long-time devotees finally have the ability to focus on the detailed, time-intensive project that is sourdough bread, a process that can take up to 36 hours, depending on the method you choose.

Building on a more niche trend that started in the late 2000s of growing interest in whole grain and artisanal baking, sourdough loaves, and their “crumb shots,” have now hit the mainstream and become the it social media photo.Bakers have turned into mini-celebritiesand there’s even afictional novel mockumenting the sourdough baking boom. Over the past few months, Google searches for sourdough more than doubled, use of the #sourdough hashtag increased 100 percent on social media, peaking in early April, and many online retailers and grocery stores have seentemporary flour shortages. These days, it seems you haven’t really baked if you haven’t baked sourdough. But as the pros know, and the new bakers quickly find out, with all that sourdough baking comesthe waste of the sourdough discard.

Building a strong sourdough starter — a mixture of water and flour that yields natural bacteria and wild yeast, which both give that signature sour flavor and leaven the dough — requires frequent “feeds” of freshwater and flour to encourage active yeast and bacterial growth. During the feeding process, a portion of the starter — known as the “discard” — is generally tossed away.

Luckily, there are ways to reduce or cut out that waste, by either storing the sourdough starter in a way that eliminates the need for a discard step or using one of the many recipes that feature the discarded sourdough starter, including biscuits, crackers, pancakes and more. Use our guide to understand the best ways to maintain and store sourdough starters, and explore our list of sweet and savory recipes to make use of your sourdough starter discard.

Storing Sourdough Starter to Reduce Food Waste

Once you’ve begun baking with your starter, there are several ways to store it to reduce how often you go through the feeding and discard steps.

If you follow this method, you will end up with sourdough discard once a week which you can use for the recipes below. If you have a strong, vibrant starter — and don’t plan to bake in the near future — you can also refrigerate the starter for several months without feeding.

Freeze it:Sourdough starter can be stored in the freezer for up to one year. You can also store discarded sourdough starter in the freezer to use for a future recipe like many of those below.

Once completely dried, break the mixture into pieces and store in an airtight glass container.
