发酵调味品

Fermented condiments form the broadest category in the encyclopedia — 18 of 59 ferments fall here, cross-cutting the substrate-based categories (lacto-veg, dairy, soy-legume, grain). The defining feature is functional rather than biochemical: condiments are flavor concentrates used in small portions to transform dishes, contrasting with the substrate-defined categories (which group by what the raw ingredient was).

The sub-traditions within fermented condiments are diverse:

*Vinegars — produced by acetic acid bacteria (Acetobacter aceti* primarily) converting ethanol to acetic acid. Apple cider vinegar from fermented apple cider; balsamic vinegar (Aceto Balsamico Tradizionale di Modena) from cooked grape must aged in a battery of woods; black rice vinegar (Zhenjiang, Hengshun 1840) from a complex grain-and-rice-bran ferment; white wine vinegar from fermented wine. Each tradition produces a distinct flavor profile despite the shared biochemistry.

*Fish-and-protein sauces* — Roman garum (and its descendants: liquamen, allec, muria) traces a continuous tradition through colatura di alici (Italy) to Southeast Asian nam pla (Thailand) and nuoc mam (Vietnam). The biochemistry is enzymatic protein hydrolysis: small fish + salt + months/years → amino-acid-rich liquid. Phu Quoc (Vietnam) and Tiparos (Thailand) represent geographically-protected continuous traditions.

*Soy/legume pastes (cross-listed)* — shoyu, tamari, doenjang, gochujang, doubanjiang, douchi, furu — these also appear in soy-and-legume but function as condiments. Their cross-listing recognizes their dual identity.

*Fermented hot sauces* — modern (Tabasco's lacto-fermented mash tradition) and traditional (Mexican fermented chiles, Korean gochujang). The lacto-fermentation tames raw chili harshness while developing umami.

*Preserved citrus and produce* — Moroccan preserved lemons, giardiniera, fermented salsa. These sit at the boundary between lacto-vegetable preservation and condiment use; their cross-listing reflects their dual function.

*Cured fish* — gravlax (Scandinavian salt-and-dill-cured salmon). Cross-listed with lacto-vegetable because the curing process involves some bacterial contribution alongside the salt-driven dehydration.

The category serves as the umbrella under which the encyclopedia's most concentrated, most-loved-in-small-doses ferments live. A teaspoon of fish sauce, a half-tablespoon of gochujang, a few drops of fermented hot sauce — these are the multipliers that turn a competent dish into a vivid one. Many global cuisines depend on a small number of fermented condiments to provide the umami backbone that the cuisine builds on.
