Salt, water and time turn cabbage, carrots and more into tangy, gut-friendly ferments that keep for months.

Fermenting is preservation at its simplest – no heat, no vinegar, just salt, water and the patience to let friendly bacteria do the work. The result isn't just long-keeping veg, it's a tangy transformation that's brilliant for your gut.
The basic technique is plain: finely slice or grate veg, massage it with salt until it releases liquid, pack it tightly into a jar with the liquid covering it, and leave at room temperature. In a week or two you have a live, tangy ferment.
Sauerkraut (cabbage), kimchi-style carrots and radish, and salt-brined beans and courgettes are all variations on the same idea.
The one rule worth being strict about is keeping the veg fully submerged beneath the liquid. Exposed bits can spoil. Weigh the veg down with a clean cabbage leaf, a weight or a tightly stuffed jar, and it stays safe.
Use the right amount of salt (around 2–3% of the vegetable weight is a good starting point) and non-iodised salt – iodised salt can inhibit fermentation. Too little salt risks spoilage; too much, and it won't ferment properly.
Once the ferment tastes good to you, move the jar to the fridge. Cold storage slows the fermentation right down, so it keeps for months while the flavour continues to deepen. A well-made ferment is one of the most reliable long-keepers in the kitchen.
