Small-Batch Fermented Sauerkraut

You don't need a heavy crock to make kraut. A quart-sized glass jar is enough to learn the rhythm of the ferment, turning raw cabbage into a bright, biting staple.

Before you start

Watch the brine levels.

The cabbage must remain submerged under its own liquid at all times. If it pokes above the surface, it will spoil.

  • Large mixing bowl
  • Quart-sized wide-mouth glass jar
  • Kitchen scale
  • Glass weight or a small ziptop bag for a follower
Ingredients

What goes in.

  • 2 lbsgreen cabbage, cored and shredded thin
  • 20 gfine sea salt (non-iodized)
The key technique

Breaking down the cell walls

Firmly squeeze handfuls of salted cabbage in the bowl until your hands are wet and a pool of brine collects at the bottom. This process takes at least ten minutes of dedicated effort.

Step by step

The method.

  1. Weigh the cabbage

    Use your scale to ensure you have exactly 20 grams of salt for every 1000 grams of cabbage; this 2% ratio is the standard for a safe, steady ferment.

  2. Massage and pack

    Once the cabbage is limp and releasing plenty of liquid, pack it into the jar. Press down firmly with your fist after every handful to eliminate air pockets.

  3. Submerge

    Pour the remaining brine from the bowl over the packed cabbage. Place a weight or a water-filled plastic bag on top to keep the solids beneath the liquid line.

  4. Ferment

    Seal the lid loosely and keep the jar out of direct sunlight at room temperature. Burp the jar daily for the first week to release carbon dioxide.

Variations

Other turns to take.

Caraway Kraut

Add one tablespoon of toasted caraway seeds during the packing stage for an earthy, traditional profile.

Spicy Chili Kraut

Incorporate one thinly sliced habanero or a teaspoon of red pepper flakes to introduce heat.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Always use non-iodized salt, as iodine can sometimes interfere with the fermentation process.

Tip

If the jar smells fresh and acidic, it is working; if it smells like sulfur or rot, discard the batch.

Tip

Place the jar on a small plate; brine often overflows during the first few days of active bubbling.

Questions

The ones that keep coming up.

How do I know when it is finished?

Taste it after two weeks. If the crunch is still there but the flavor has turned sharp and sour, move it to the refrigerator to slow the process down.
