Sichuan Province — pao cai jars are found in virtually every Sichuan household and restaurant
Sichuan's salt-brine vegetable fermentation in a water-sealed ceramic jar (pao cai guan). Unlike Korean kimchi (no seafood paste, no pepper paste), Sichuan paocai uses pure salt brine with aromatics — Sichuan pepper, dried chili, ginger, garlic. Results in crisp, sour, mildly spiced pickled vegetables fermented in 1–3 days.

{"Water seal on jar creates anaerobic environment — essential for lacto-fermentation","Salt ratio: 2–3% of water by weight for optimal lacto-fermentation","Do not disturb jar during fermentation","Brine can be maintained indefinitely — 'mother' brine improves with age"}
{"Best vegetables: napa cabbage, carrots, green beans, radish, young ginger","Add a splash of baijiu (white spirit) to inhibit harmful bacteria","Aged brine (lao luo zi) from 10+ year jars is prized — used to start new batches"}
{"Breaking water seal during fermentation — allows air in, risks spoilage","Too much salt — inhibits fermentation, overly salty result","Not maintaining brine 'mother' — discarding aged brine loses valuable culture"}
