Yuzu Kosho Fresh Chili Citrus Paste Kyushu

Oita Prefecture, Kyushu; traditionally home-produced in citrus-growing regions; now nationally distributed

Yuzu kosho is a fresh condiment paste from Kyushu—particularly Oita Prefecture—made from the zest and juice of unripe yuzu citrus combined with fresh chili pepper (aotougarashi or red chili) and salt, which is allowed to ferment briefly. The result is one of Japanese cooking's most complex and vivid condiments: intensely aromatic yuzu fragrance, fresh chili heat, salt-fermented depth, and a green or red color depending on which chili is used. Green yuzu kosho (made with unripe green yuzu and green chili) is the most traditional form—sharper, grassier, and more aromatic; red yuzu kosho uses ripe red chili for a richer, slightly sweeter profile. The preparation requires zesting unripe yuzu (the fragrant white pith avoided) and combining with minced fresh chili in a mortar or processor, then salting heavily and allowing to sit for several days where the salt draws out moisture and light fermentation develops. Yuzu kosho's applications are now extensive far beyond its Kyushu home: as a condiment for nabe hot pot, with grilled meats, mixed into dressings and marinades, with sashimi instead of wasabi, stirred into miso for a compound condiment. Its combination of citrus fragrance and heat is unlike any other condiment globally.
