You should always have a lid on your sourdough discard jar. Ideally sourdough discard should be stored in the fridge for up to two weeks. During this time, you want to ensure that it is securely covered with a sealed lid so that it does not absorb smells or debris from inside the fridge.
While the temperature and surroundings of a starter are crucial to its outcome, the sourdough starter does not need to be sealed in an airtight container. It's still helpful to cover the starter with some sort of a lid, to prevent any mess from ensuing (via The Perfect Loaf).
If you aren't intending to use your sourdough starter every day, it is best kept in the fridge. To do this, feed it as instructed above, seal the jar and then stand at room temperature for 2-3 hours (to help reinvigorate the yeast) before placing in the fridge to store.
This means that you feed one part sourdough starter to 2 parts flour and 2 parts water. This ratio will ensure that your sourdough starter has adequate food whilst it's in the fridge. So you would take 25g of sourdough starter and feed it with 50g of flour and 50g of water.
Reviving a sourdough starter that has been stored in the fridge for a longer period of time is a good idea. This can be done by feeding it equal parts flour and water, allowing it to sit at room temperature for 12 hours, and then feeding it again.
You can leave the starter in the refrigerator for 3 to 4 days at a time between feedings. We recommend feeding sourdough starter at least twice a week for best results. Remember, if you're planning to make bread on a given day, you'll feed sourdough starter the night before you bake.
It will need a lid or cover, but not something airtight: Sourdough starter emits gas, and a sealed canister can explode. If you have intermittent baking plans, you may want something that can be lidded more tightly and stashed in the refrigerator.
Your starter needs to be fed about 1x per week if refrigerated, and every day if left at room temperature. Generally, about 5-6 hours after feeding my starter is ready.
Yes, sourdough bread will rise in the fridge, but it won't rise as quickly as bread that contains commercial baker's yeast. While yeasted breads tend to over proof if left in the fridge overnight, you can usually leave sourdough bread in the fridge for up to 24 hours without the risk of it over proofing.
People often worry if they've killed their starter by leaving it in the refrigerator for a long time without feeding it. When it's refrigerated, the yeast slows down and becomes practically dormant. A yellowish liquid usually forms on top, referred to as "hooch" by sourdough folks.
While mold on a sourdough starter is fairly rare, it does happen from time to time. You can check our sourdough starter for sale to start making sourdough bread. The cause is usually some sort of contamination with food or soap residue or weakened yeast due to a forgotten feeding.
Oxygen: Fermenting sourdough starters will produce carbon dioxide. The starter should be loosely covered in order to safely release the gas, but the culture does not require oxygen.
What kind of container should you use to store sourdough starter? Pellegrinelli says the fermentation process of sourdough starter will corrode metal. Therefore, she recommends storing sourdough starter in a plastic or glass container.
Tin foil can be used to cover dough rising or dough that has been rolled out and is ready to be cut into shapes. Tin foil can also store the dough in the refrigerator or freezer.
When you need to use your starter, you can use it straight from the fridge or let it come to room temp first if you want. If you use it straight from the fridge, it will just add a few minutes to your dough proofing time.
You must discard some of your sourdough starter each time you feed it. You'll discover that discarding is necessary to build a healthy and thriving sourdough starter - but it's not actually as wasteful as you might think.
The rule of any kitchen is “When in doubt, throw it out,” but I wouldn't panic and toss your starter if you only missed 1-3 days of feeding. If it's more than 3 days AND you have a warm kitchen, you'll have to make the call based on how well you know your starter.
Allow the starter to rest at room temperature (about 70°F) for at least 2 hours; this gives the yeast a chance to warm up and get feeding. After about 2 hours, replace the starter in its storage container and refrigerate.
You can cover it loosely with a lid, plastic wrap, or even a small cloth. I go back and forth depending on my mood. Keep in mind, the jar might burst if the lid is on too tight which means you'll run the risk of getting glass shards in the mixture.
Once it doubles and bubbles within 8 hours of feeding, it's ready to use in a recipe or go into the refrigerator for long-term storage, where you'll only need to feed it once a week. Speaking of storage, check out this stoneware sourdough crock.
Cover the sourdough starter with cheesecloth and let stand at room temperature for 3-5 days, stirring three times daily. The starter is ready for use when it smells fermented and the vigorous bubbling ceases.
What if I miss feeding my sourdough starter? If you miss one of your starter feedings, it'll be just fine. Give it a feeding when you next remember it needs one, and continue with your daily feedings as usual.
A mature sourdough starter can last for several weeks to months if kept in a refrigerator without being fed. If your sourdough starter has been in the fridge for a while and you want to give it a refresh, follow the steps below. Discard all but 25 grams and add 100 grams of filtered water and 100 grams of flour.
Frequently Asked Questions. Do you cover sourdough in the fridge? Ideally you should place a plastic shower cap over the banneton while the dough cold proofs in the fridge. You could also place the sourdough into a plastic bag to stop it drying out.
