Curtido (El Salvador fermented cabbage slaw)

El Salvador — the canonical pupusa accompaniment; also eaten with other Salvadoran dishes

Curtido is El Salvador's essential fermented cabbage condiment — finely shredded cabbage, carrot, and white onion fermented briefly (2–24 hours) in salted water with dried oregano and lime juice. It is the canonical accompaniment to pupusas. Unlike sauerkraut, curtido is only lightly fermented (not fully soured) and retains a fresh crunch. The salt draws water from the vegetables and begins the lacto-fermentation; the lime adds brightness. Served cold alongside warm pupusas.

Lightly sour, fresh, herbal, slightly tart from lime — crisp and cooling; the essential counterpart to the rich pupusa

{"Salting and pressing the cabbage before the fermentation step is essential — draws excess water and begins softening","Oregano (dried Mexican oregano, not Mediterranean) is the defining herb","2–24 hour fermentation at room temperature — short ferment for crunch, longer for more sour notes","Shredding consistency: fine (2–3mm) — thick shreds do not absorb the brine properly","Serve cold — the temperature contrast with the hot pupusa is intentional and important"}

{"For faster curtido (under 1 hour): pour boiling water over the shredded vegetables for 30 seconds, drain, add brine — wilts quickly","The brine ratio: 1 cup warm water + 1 tsp salt + juice of 1 lime per 2 cups cabbage","Curtido keeps refrigerated for up to 2 weeks — improves with 24 hours of rest","For restaurant service: make a batch every 2–3 days to maintain freshness and correct fermentation level"}

{"Insufficient salt in the initial ferment — doesn't draw water and doesn't ferment","Over-fermentation — should be lightly sour, not fully fermented like sauerkraut","Using Mediterranean dried oregano — different flavour compound profile than Mexican oregano","Thick shredding — affects brine absorption and textural experience"}
