Fermenting Vegetables in Small Batches
Small-batch fermentation removes the intimidation of large crocks and long timelines. It allows you to experiment with single jars of whatever is currently at its peak.
Salt is your only safeguard against spoilage.
Use a digital scale to weigh your vegetables and salt. Aiming for 2% salinity by weight ensures the good bacteria thrive while the bad ones stay dormant.
- Digital kitchen scale
- Wide-mouth glass mason jar
- Glass fermentation weight or a small cabbage leaf
- Clean cloth and rubber band
What goes in.
- 500gHard vegetables like carrots, radishes, or cabbage
- 10gNon-iodized sea salt (exactly 2% of vegetable weight)
- as neededFiltered water (only if produce doesn't release enough juice)
Keep it under the brine
Anything exposed to air will mold. Use a weight to keep every piece of vegetable beneath the surface of the liquid at all times.
The method.
Prep the vegetables
Slice, shred, or dice your vegetables into uniform pieces. Smaller pieces ferment faster and pack tighter.
Calculate and massage
Weigh the vegetables and calculate 2% of that weight for your salt. Sprinkle the salt over the vegetables in a bowl and massage firmly for several minutes until they release their own liquid.
Pack the jar
Transfer the vegetables to the jar, pressing down firmly after every handful to eliminate air pockets. The brine should rise above the vegetables.
Weight and cover
Place your weight on top of the vegetables to ensure they stay submerged. Cover the jar opening with a clean cloth secured by a rubber band to keep out dust while allowing gases to escape.
Ferment and taste
Leave the jar in a cool, dark spot out of direct sunlight. Begin tasting after 5 days; move it to the refrigerator once it reaches the level of acidity you prefer.
When it doesn't go to plan.
Always use non-iodized salt, as iodine can inhibit the growth of the beneficial bacteria you want to encourage.
If your vegetables aren't juicy enough to cover themselves after massaging, add a brine made of 20g salt per 1 liter of water.
Keep a dedicated notebook with weights and dates; fermentation is sensitive to room temperature, and small changes in your kitchen environment will alter the timeline.
The ones that keep coming up.
What if white foam appears on the surface?
This is often kahm yeast. It is harmless but can affect the flavor. Skim it off, ensure everything remains submerged, and keep going.
How do I know when it is finished?
The transformation is finished when the vegetables have lost their raw snap and developed a distinct, sharp acidity that you enjoy.
