Sourdough is not just a type of bread, it’s a way of life for many bakers. But what happens when your sourdough starter ends up in the freezer and you want to revive it? Don’t worry, it’s not the end of the world!
Reviving a frozen sourdough starter is a simple process that requires a little bit of time and patience. The key is to gradually bring your starter back to life without shocking it with extreme temperature changes.
First, take the frozen sourdough starter out of the freezer and let it thaw at room temperature. This might take a few hours or overnight, depending on the size of your starter. Once it is completely thawed, transfer it to a clean jar or container.
Next, it’s time to wake up your starter! Start by feeding it with equal parts of flour and water. For example, if you have 100 grams of starter, add 50 grams of flour and 50 grams of water. Mix well to ensure that the flour and water are fully incorporated.
How to Revive a Frozen Sourdough Starter
If you’ve stored your sourdough starter in the freezer and want to bring it back to life, here’s a step-by-step guide to revive it:
- Thawing: Start by transferring your frozen sourdough starter to the refrigerator. Allow it to thaw slowly overnight or for about 12 hours.
- Gradual Feeding: Once thawed, transfer the starter to a clean glass or ceramic container. Begin by discarding all but a small amount of the starter – about 1-2 tablespoons.
- Feeding Schedule: Now, add equal parts of water and bread flour to the remaining starter. For example, if you have 1 tablespoon of starter, add 1 tablespoon of water and 1 tablespoon of flour.
- Mixing: Use a clean spoon or whisk to mix the water, flour, and starter until well combined. Make sure there are no dry flour pockets left in the mixture.
- Resting: Cover the container loosely with a cloth or plastic wrap and let it sit at room temperature – preferably in a warm spot, for 24 hours. This allows the wild yeast to start fermenting and revitalizing.
- Feeding & Discarding: After 24 hours, discard about half of the starter and repeat the feeding process by adding equal parts of water and flour again. Mix well and let it rest for another 24 hours.
- Repeat and Maintain: Continue feeding and discarding the starter daily or every 12 hours until it becomes active, bubbly, and doubles in size within a few hours of feeding. This may take anywhere from 3 to 7 days.
Remember to use a clean container and utensils for each feeding, and maintain your starter by feeding it regularly even after it has revived. Once your sourdough starter is active and healthy, you can use it to bake delicious bread and other sourdough treats.
Gather your frozen sourdough starter
Reviving your sourdough starter from the freezer is a simple process that begins with gathering your frozen starter. Start by putting on some gloves to protect your hands from the cold as you handle the frozen dough. Then, carefully remove the container with your frozen starter from the freezer.
Inspect the container for any signs of damage or leakage. It’s important to ensure that the container is intact to prevent any contamination or loss of the starter. If you notice any cracks or damage, transfer the frozen starter to a new, airtight container before proceeding.
Once you have confirmed that the container is undamaged, place it on a clean, kitchen countertop. Allow the container to sit at room temperature for several hours or overnight to thaw the frozen starter. Be patient during this process, as it may take some time for the starter to fully thaw.
While the starter is thawing, take the opportunity to gather the rest of the ingredients you’ll need for refreshing and feeding your starter. This typically includes flour and water.
By gathering your frozen sourdough starter and allowing it to thaw, you’ll be one step closer to reviving a thriving and active sourdough starter that’s ready to use for baking delicious bread.
Thaw the sourdough starter
Once you are ready to revive your sourdough starter, it is important to thaw it properly. Remove the frozen container from the freezer and let it thaw slowly in the refrigerator. This will prevent any temperature shock to the live yeast cultures. Thawing in the refrigerator may take up to 24 hours, so plan accordingly.
It is not recommended to thaw the sourdough starter at room temperature or in a warm area, as this can cause the yeast cultures to wake up too quickly. Thawing too quickly may result in off-flavors or even the death of the live yeast cultures.
During the thawing process, condensation may occur inside the container. This is normal and should not be a cause for concern. However, be sure to carefully drain any excess liquid before proceeding to the next step.
Once the sourdough starter has thawed completely and any excess liquid has been drained, it is ready to be revived. Follow the next steps in the revival process to bring your sourdough starter back to life.
Feed the thawed starter
Once your sourdough starter has thawed, it’s important to give it a good feeding to revive its activity. Start by discarding all but a small amount of the thawed starter, ideally leaving about 100 grams in the container. Discarding some of the starter helps to maintain a good balance of yeast and bacteria, as well as preventing the starter from becoming too large.
Next, add 100 grams of water (at room temperature) to the container and stir it into the remaining starter until well combined. Then, add 100 grams of flour (all-purpose or bread flour) to the mixture and stir until no dry spots remain. You can use a spoon or your clean hands to mix the ingredients together.
Once the water and flour are thoroughly mixed in, cover the container loosely with a clean kitchen towel or plastic wrap. Place the container in a warm spot in your kitchen, ideally between 70-85°F (21-29°C). The warm temperature will help to encourage the growth of yeast and bacteria in the starter.
Leave the starter to ferment for about 12 hours, and then give it another feeding by discarding all but a small amount and repeating the process of adding water and flour as described above. This second feeding helps to further activate the starter and build up its strength.
Continue feeding the starter every 12 hours, discarding some of the starter each time, and refreshing it with equal amounts of water and flour. After a few days of consistent feeding, your sourdough starter should be fully revived and ready to use in your bread recipes.
Allow the starter to rise
Once you have taken your sourdough starter out of the freezer and brought it to room temperature, it’s time to allow it to rise. This process may take several hours or even a day, depending on the condition of your starter.
Start by giving your starter a good stir to re-incorporate any liquid that may have separated during freezing. Then, transfer a small portion of the starter to a clean bowl or jar. Feed it with equal parts flour and water by weight (for example, 50 grams of flour and 50 grams of water) and mix well.
Cover the bowl or jar with a clean cloth or plastic wrap and let it sit at room temperature. You may notice bubbles forming and the starter increasing in volume over time. This is a good sign that your starter is coming back to life.
During this rising phase, it’s important to maintain a consistent feeding schedule. Every 12 hours, discard a portion of the starter and feed it with fresh flour and water. This helps to keep the yeast and bacteria in the starter healthy and active.
Continue this process until your starter is consistently doubling in size within a few hours of each feeding. This indicates that your starter is active and ready to be used in bread recipes again.
Use a Portion of the Starter for Baking
If your sourdough starter has successfully revived after being frozen, you can now use a portion of it to bake delicious bread or other sourdough-based recipes. Here’s how:
1. Measure the Desired Amount
Before using your revived sourdough starter, you’ll need to measure out the desired amount of starter for your recipe. If you plan to bake bread, you’ll typically need 1 cup of active starter. If you need more or less, adjust accordingly.
2. Preparing the Starter
Once you’ve measured out the desired amount of revived sourdough starter, remove it from the rest of the starter and transfer it to a clean bowl. Give the starter a good stir to recombine any liquid that may have separated during freezing or revival.
3. Feeding the Starter
To ensure that your revived sourdough starter is at its peak of activity, it’s a good idea to give it a feeding before using it for baking. This will strengthen the starter and enhance its flavor. Feed the starter in the same way you would feed a regular unfrozen starter by adding equal parts of flour and water and stirring well. Allow the starter to sit at room temperature for several hours or overnight until it becomes bubbly and active.
Note: If your starter shows signs of sluggishness after being revived, you may need to feed it multiple times to fully revive its activity.
4. Incorporating the Starter into Your Recipe
Once your sourdough starter is bubbling and active, you can proceed to incorporate it into your recipe. Follow your sourdough recipe as normal, replacing the portion of unfrozen starter with your newly revived starter. Remember to adjust the flour and water ratios in the recipe to accommodate for the water and flour in your revived starter.
Tip: To ensure a strong and flavorful sourdough taste, it’s generally recommended to feed your revived starter a few times before using it for baking.
By following these steps, you can successfully use a portion of your revived sourdough starter for baking delicious bread and other sourdough-based recipes.
Store the remaining starter
Before reviving your sourdough starter from the freezer, it’s important to store any remaining starter properly. This will ensure that you have a backup in case anything goes wrong with the revival process.
To store the remaining starter, you will need a clean and airtight container. A glass jar or a plastic container with a tight-fitting lid will work well. Make sure the container is thoroughly cleaned and dried before transferring the starter.
First, remove any excess liquid from the starter. Pour off any hooch, which is a clear liquid that may have formed on top. Then, transfer the remaining starter to the container. Make sure to scrape down the sides of the container to remove any starter residue.
Next, cover the container with the lid and store it in the refrigerator. The cold temperature will help slow down the fermentation process and keep the starter dormant. It’s important to note that the starter will still become less active over time, so it’s a good idea to check on it periodically.
Depending on how often you use your starter, you can store it in the refrigerator for up to a couple of weeks. If you plan on not using the starter for an extended period, you may consider freezing it instead. To freeze the starter, transfer it to a freezer-safe container and label it with the date.
Remember to take out a portion of the starter for revival before freezing it. This will ensure that you have a backup to work with.
Maintain and care for your revived sourdough starter
Reviving your sourdough starter is just the beginning. To ensure its longevity and optimal performance, it is important to maintain and care for it regularly.
Feed it regularly: Like any living organism, your sourdough starter needs food to stay alive. Feed it at least once a week by discarding a portion of the starter and refreshing it with equal parts flour and water.
Keep it at the right temperature: Sourdough starters prefer a slightly warm environment to thrive. A temperature between 21-24°C (70-75°F) is ideal for maintaining the activity of the yeast and lactic acid bacteria in your starter.
Store it in the fridge: If you’re not planning on baking with your sourdough starter frequently, store it in the fridge. This will slow down its fermentation and reduce the need for regular feedings. Take it out of the fridge and feed it at least once a week to keep it alive and active.
Use it regularly: Sourdough starters need to be used regularly to stay healthy and maintain a robust population of yeast and bacteria. Even if you’re not baking every day, try to use it at least once a week to keep it active and prevent it from developing off-flavors.
Observe and adjust: Pay attention to the changes in your sourdough starter. If it becomes too thick or too thin, adjust the hydration level by adding more flour or water respectively. Similarly, if it becomes too sour or weak, you can make adjustments by changing the feeding ratio or frequency.
Share it: Sourdough starters have a long history of being shared among bakers. Share a portion of your revived sourdough starter with friends or family, or even start a sourdough exchange in your community. Sharing not only spreads the joy of baking but also ensures the preservation of unique strains of yeast and bacteria.
Maintaining and caring for your revived sourdough starter requires attention and regular feeding, but the rewards are worth it. With proper care, your sourdough starter can become a reliable companion in your baking adventures for years to come.
