Making sauerkraut at home is simple, requires minimal ingredients, and yields delicious results. Here’s an effective method:
1 medium cabbage (about 2-3 pounds)
1-3 tablespoons of salt (use sea salt or kosher salt, avoid iodized salt)
Large mixing bowl
Cutting board and knife (or mandoline)
Wide-mouth mason jar or fermentation crock
A smaller jar or weight to press the cabbage down
Clean cloth or paper towel
Rubber band
Prepare the Cabbage:
Remove the outer leaves and set one large leaf aside.
Cut the cabbage into quarters and remove the core.
Slice the cabbage thinly or shred it, depending on your texture preference.
Salt the Cabbage:
Place the cabbage in a large bowl and sprinkle the salt evenly over it.
Massage the cabbage with your hands for about 5-10 minutes. This will draw out the water and create a brine.
Pack the Jar:
Transfer the salted cabbage into a mason jar or fermentation crock, pressing it down firmly with your hand or a tamper to eliminate air pockets.
Pour any brine from the bowl into the jar to ensure the cabbage is fully submerged.
Add a Weight:
Use the reserved outer cabbage leaf to cover the shredded cabbage, tucking it around the edges.
Place a smaller jar, fermentation weight, or clean stone on top to keep the cabbage submerged under the brine.
Cover and Ferment:
Cover the jar with a clean cloth or paper towel secured with a rubber band to keep out dust and pests.
Set the jar in a cool, dark spot (around 65-75°F) to ferment.
Monitor the Fermentation:
Check daily to ensure the cabbage remains submerged. If needed, press it down to release more brine or add a little salted water (1 tsp salt per cup of water).
Taste and Store:
Start tasting the sauerkraut after 5-7 days. Fermentation can take 1-4 weeks, depending on your preference for tanginess and the ambient temperature.
Once it's tangy enough, transfer it to the fridge to slow down fermentation. Sauerkraut can last for several months refrigerated.
Ensure everything is clean to prevent contamination.
Avoid overpacking the jar; leave some space at the top for the kraut to expand.
If white foam or scum appears on the surface, skim it off—it’s harmless.
Experiment with add-ins like caraway seeds, garlic, ginger, or shredded carrots for flavor variations.
Sauerkraut should not be sealed with a tight lid during fermentation because it produces carbon dioxide, and sealing it can cause pressure buildup, potentially leading to an explosion or mold growth due to trapped moisture. Here's why and what works better:
Fermentation is an anaerobic process, but the carbon dioxide needs a way to escape.
A sealed environment without a gas release mechanism can lead to spoilage or safety risks.
Cloth or Paper Towel:
Use a clean cloth or paper towel secured with a rubber band.
This keeps dust and pests out while allowing gases to escape.
Fermentation Lids or Airlocks (if available):
These are specialized lids with vents or airlocks that let carbon dioxide escape without letting oxygen in.
They're ideal for mason jars if you plan to ferment regularly.
Loose Lid and Ring:
If you only have a lid and ring, screw it on loosely to allow gases to escape.
Do not tighten it all the way.
Plastic Wrap as a Temporary Fix:
You can place plastic wrap over the top and secure it with a rubber band, but this isn't ideal since it traps moisture and can encourage mold if not closely monitored.
The key is maintaining a balance: the cabbage must stay submerged under the brine (anaerobic environment), but gases need a safe escape route.
