Lacto-fermentation is the oldest form of food preservation — just vegetables, salt, and wild bacteria that are already on every surface. The result is probiotic-rich, enzyme-active food that keeps for months without refrigeration and improves gut health with every bite.
What You Need
- Any firm vegetables: cabbage, carrots, beets, radishes, cucumbers, green beans
- Non-iodized salt (sea salt or kosher salt)
- Ratio: 2% salt by weight of vegetables (20g salt per 1kg vegetables)
- Optional aromatics: garlic, dill, peppercorns, bay leaves, caraway, hot peppers
Method
- Weigh your vegetables. Calculate 2% of that weight in salt.
- Shred, slice, or leave whole (smaller pieces ferment faster).
- Massage salt into shredded vegetables (like sauerkraut) until they release brine, OR dissolve salt in water and pour over whole/sliced vegetables.
- Pack tightly into a clean glass jar, pressing down firmly so the brine rises above the vegetables.
- Keep vegetables submerged below the brine — use a zip-lock bag filled with brine, a small jar, or a dedicated weight.
- Cover loosely (cloth or loose lid) and leave at room temperature (65–75°F).
- Taste daily from day 3. Transfer to the refrigerator when tangy to your liking. This slows fermentation.
- Fermentation is complete in 3–7 days at warm temperatures, 2–4 weeks at cooler temps.
Tips & Notes
- Brine going cloudy is normal and good — it's full of beneficial bacteria.
- If you see white film (kahm yeast) on top, simply skim it off. It's harmless but can cause off-flavors.
- The only sign of failed fermentation is mold with fuzzy growth — fuzzy = discard, slimy/cloudy = safe.
