Sauerkraut

The canonical lacto-fermented vegetable. Finely shredded green cabbage, salted at 2% by weight, massaged until it releases its own brine, then packed below the liquid line and fermented 2-4 weeks at room temperature. No added water — cabbage self-brines.

Technique

Shred cabbage 2-3mm thick. Weigh. Add 2% salt by weight. Massage 8-12 minutes until cabbage wilts and liquid pools freely (~2 cups per kg). Pack tight into crock or jar, pressing down to remove air pockets and ensure cabbage is submerged under brine. Weigh down with a glass weight or cabbage leaf + small jar of water. Cover loose (towel + rubber band OR airlock lid). Ferment 65-72°F. Taste weekly from day 7. Ready when tangy, translucent, softly crisp — usually 14-28 days.
