Canning sauerkraut after fermentation not only extends its shelf life but also preserves the tangy, flavorful punch that makes this dish a favorite across many cultures. Whether you're a seasoned canner or a curious beginner, this guide will walk you through everything you need to know about the process—while highlighting the rich history and cultural significance of sauerkraut.
The Story Behind Sauerkraut
Sauerkraut, which means "sour cabbage" in German, has been enjoyed for centuries. Its origins can be traced back to China over 2,000 years ago, where fermented cabbage was used as a food preservation technique. The dish made its way to Europe through trade, becoming especially popular in Germany and other countries. Not only is sauerkraut delicious, but it’s also packed with probiotics, vitamins, and minerals that support gut health.
Why Can Sauerkraut?
Canning sauerkraut is an excellent way to preserve its bright flavor and health benefits. By sealing the sauerkraut in jars, you can enjoy the taste of homemade ferments long after cabbage season is over.
Preparation Tips Before You Can
Selecting the Right Cabbage
- Choose Fresh: Always start with fresh, firm heads of cabbage. The better the cabbage, the better the sauerkraut. Look for cabbage that feels heavy for its size and has vibrant green leaves.
- Organic is Best: If possible, choose organic cabbage to avoid any unwanted pesticides that could interfere with fermentation.
Ingredients for Perfect Fermentation
- Salt: Use non-iodized salt (like sea salt or kosher salt) to avoid any additives that could harm the fermentation process. A good rule of thumb is 3 tablespoons of salt per 5 pounds of cabbage.
- Optional Add-ins: Caraway seeds, juniper berries, or even a splash of apple cider vinegar can elevate the flavor profile of your sauerkraut.
The Fermentation Process
Step-by-Step Guide to Fermenting
- Shred the Cabbage: Remove the outer leaves, then slice the cabbage into thin strips.
- Mix with Salt: Combine the shredded cabbage with salt in a large bowl. Massage the cabbage until it releases its juices.
- Pack into Jars: Transfer the cabbage into sterilized jars, pressing down firmly to ensure it’s submerged in its own juice.
- Seal and Store: Cover the jars with a cloth or lid. Let them ferment at room temperature for 1-4 weeks, tasting occasionally until it reaches your desired flavor.
Fun Fermentation Facts
- Timing is Everything: The fermentation process can vary based on temperature and the salt concentration. Warmer temperatures speed up fermentation, while cooler ones slow it down.
- Bubbles of Joy: Don’t be alarmed if you see bubbles! This is a sign that the beneficial bacteria are doing their work.
Canning Your Sauerkraut
Timing Your Canning Process
Once your sauerkraut has fermented to your liking, it's time to can it. Make sure to do this within a week of reaching your desired flavor to maintain freshness.
Step-by-Step Canning Instructions
- Sterilize Your Jars: Before canning, sterilize jars and lids in boiling water.
- Heat the Sauerkraut: Bring your fermented sauerkraut to a gentle simmer over low heat, ensuring it’s heated through.
- Pack the Jars: Using a funnel, carefully pack the hot sauerkraut into the sterilized jars, leaving about 1 inch of headspace.
- Seal the Jars: Wipe the rims of the jars clean, place the lids on, and screw on the bands until they're fingertip-tight.
- Process the Jars: Place the jars in a water bath canner and process for 15-20 minutes, depending on your altitude (adjust for high altitudes as needed).
- Cool and Store: Remove the jars and let them cool completely. You should hear a satisfying “pop” as the lids seal. Once cooled, store them in a cool, dark place.
