02How to do it
- 1Work clean and use the right salt ratio (often 2–3% by weight for vegetables).
- 2Submerge the food fully under its brine, away from air.
- 3Hold at a steady, cool room temperature.
- 4Taste over days to weeks until the acidity and funk are right, then refrigerate.
03Doneness & pitfalls
Doneness cues
- A clean sour smell, a tangy taste, and (for brines) cloudy liquid with small bubbles.
Common mistakes
- Exposure to air invites mold — keep everything submerged.
- Too little salt lets spoilage organisms win.
- Too warm ferments too fast and turns mushy or off.
