Canning Homemade Sauerkraut: A Time-Honored Tradition

The smell of fermenting cabbage always takes me back to my grandmother’s cellar. Jars lined the shelves, filled with the bounty of her garden, each a promise of the flavors of summer in the cold winter months. The tangy, slightly sour scent of sauerkraut, bubbling gently under its weighted lid, was as familiar and comforting as her warm hugs. She taught me that making sauerkraut wasn’t just about preserving food; it was about preserving tradition, family, and the love that went into every bite.

Recipe Overview

• Cook Time: 30 minutes
• Total Time: 3-6 weeks, 2 hours and 30 minutes
• Yield: Approximately 12 quarts
• Dietary Type: Vegan, Gluten-Free, Dairy-Free

Ingredients

• 50 lbs mature cabbage heads
• 1 lb canning salt

For the Brine (if needed):

• 1 1/2 tablespoons canning salt
• 1 quart water

Equipment Needed

• Large pickling container (crock, food-grade bucket)
• Sharp knife or cabbage shredder
• Large mixing bowls
• Wooden spoon, tamper, or clean hands
• Muslin or cheesecloth
• Weight (plate, jar filled with water)
• Large pot
• Canning jars (pint or quart)
• Canning lids and rings
• Jar lifter
• Boiling water canner

Instructions

1. Begin by selecting firm, mature heads of cabbage. Remove the outer leaves and discard any undesirable portions. Wash and drain the cabbage thoroughly.

2. Cut the cabbage heads into halves or quarters and remove the core.

3. Using a shredder or a sharp knife, cut the cabbage into thin shreds, aiming for a thickness similar to a dime. Uniform shreds will ensure even fermentation.

4. In a large bowl, thoroughly mix 3 tablespoons of canning salt with every 5 lbs of shredded cabbage. Ensure the salt is evenly distributed to draw out moisture and initiate fermentation.

5. Let the salted cabbage stand for several minutes to wilt slightly. This step is crucial as it allows for easier packing without excessively breaking or bruising the delicate shreds.

6. Pack the salted cabbage firmly and evenly into your large, clean pickling container. A traditional stoneware crock is ideal, but a food-grade plastic bucket works as well.

7. Using a wooden spoon, tamper, or your clean hands, press down firmly on the cabbage until the juice comes to the surface. This pressing action helps release the natural sugars and liquids needed for fermentation.

8. Repeat the process of shredding, salting, and packing cabbage until the container is filled to within 3 to 4 inches of the top. Leave enough headspace for the fermentation process.

9. Check the liquid level. The cabbage should be completely submerged in its own juice. If the juice does not cover the cabbage, prepare a brine by combining 1 1/2 tablespoons of canning salt with 1 quart of water. Bring the brine to a boil, then cool it completely before adding it to the container.

10. Cover the cabbage with a clean piece of muslin or cheesecloth and tuck the edges down against the inside of the container. This will help prevent mold growth and keep the cabbage submerged.

11. Weight down the cabbage under the brine. Use a plate that fits inside the container or a jar filled with water to apply gentle pressure.

12. Allow the cabbage to ferment in a room temperature of 70 to 75 degrees F (21-24 degrees C). This temperature range is optimal for fermentation.

13. Monitor the fermentation process. The formation of gas bubbles indicates that fermentation is taking place. Remove and discard any scum formation each day to maintain a clean and healthy environment.

14. Fermentation is usually complete in 3 to 6 weeks, depending on the temperature and humidity. Taste the sauerkraut periodically to check for desired sourness.

15. TO CAN: Once the sauerkraut has reached your desired level of sourness, it’s time to can it for long-term storage.

16. Bring the sauerkraut to a simmer (185 to 210 degrees F or 85-99 degrees C) in a large pot. Do not boil the sauerkraut, as this can affect its texture and flavor.

17. While the sauerkraut is simmering, prepare your canning jars. Wash the jars and lids in hot, soapy water, and rinse thoroughly. Keep the jars hot until ready to use. You can sterilize the jars by boiling them for 10 minutes, but this is not necessary if you are processing them for the recommended time.

18. Pack the hot sauerkraut into the hot jars, leaving 1/2 inch of headspace. This headspace is crucial for proper sealing during processing.

19. Remove any air bubbles by gently tapping the jars on a towel-lined surface or using a non-metallic spatula.

20. Wipe the rims of the jars with a clean, damp cloth to remove any food residue.

21. Adjust the lids and rings according to the manufacturer’s instructions. The rings should be fingertip tight, not overly tightened.

22. Process the jars in a boiling water canner. Ensure the jars are completely submerged in boiling water. Process pint jars for 15 minutes and quart jars for 20 minutes. Adjust processing time for altitude if necessary.

23. After processing, turn off the heat and carefully remove the jars from the canner using a jar lifter. Place the jars on a towel-lined surface, leaving space between them.

24. Let the jars cool completely, undisturbed, for 12-24 hours. As the jars cool, you should hear a “pop” sound, indicating that the lids have sealed properly.

25. After 24 hours, check the seals. Press down on the center of each lid. If the lid does not flex or give, it is properly sealed. If a lid flexes, it is not sealed and should be reprocessed with a new lid, refrigerated, or frozen.

26. Remove the rings from the sealed jars, wash the jars, and label them with the date and contents. Store the canned sauerkraut in a cool, dark place.

Expert Tips & Tricks

• Use high-quality cabbage: The better the cabbage, the better the sauerkraut. Look for firm, heavy heads with tightly packed leaves.
• Don’t skimp on the salt: Canning salt is crucial for drawing out moisture and inhibiting the growth of undesirable bacteria. Do not substitute with iodized salt, as it can affect the color and flavor of the sauerkraut.
• Maintain consistent temperature: A stable temperature during fermentation is essential. Avoid placing the pickling container in direct sunlight or near drafts.
• Be patient: Fermentation takes time. Don’t rush the process. Taste the sauerkraut regularly to monitor its progress.
• Experiment with flavors: While this recipe is for traditional sauerkraut, you can add other vegetables or spices to customize the flavor. Caraway seeds, juniper berries, or garlic are popular additions.

Serving & Storage Suggestions

Canned sauerkraut can be stored in a cool, dark place for up to a year. Once opened, store in the refrigerator and consume within a week. Serve sauerkraut hot or cold as a side dish with sausages, pork, or Reuben sandwiches. It’s also delicious in soups and stews.

FAQs (Frequently Asked Questions)

Q: Can I use iodized salt instead of canning salt?
A: No, iodized salt can cause the sauerkraut to darken and have an off-flavor. Canning salt is pure sodium chloride and is essential for proper fermentation.

Q: How do I know when the sauerkraut is finished fermenting?
A: The sauerkraut is finished fermenting when it has reached your desired level of sourness. Taste it periodically, starting after 3 weeks.

Q: What if mold grows on the surface of the sauerkraut during fermentation?
A: Remove and discard any mold that forms on the surface. Ensure the cabbage is always submerged under the brine to prevent mold growth.

Q: Why is my sauerkraut mushy?
A: Mushy sauerkraut can be caused by using overripe cabbage, not using enough salt, or fermenting at too high a temperature.

Q: Can I freeze sauerkraut instead of canning it?
A: Yes, you can freeze sauerkraut. Drain off excess liquid and pack it into freezer-safe containers or bags.
