Yuzu Citrus Cultivation Aroma and Applications

Japan — yuzu cultivation primarily in Kochi Prefecture, Tokushima, and Ehime; believed to have originated in China and Korea; cultivation in Japan documented from the Nara period; the Toji (winter solstice) yuzuyu bathing tradition from the Edo period

Yuzu (柚子, Citrus junos) is Japan's most important citrus fruit — not for its juice (which is quite sour and produced in relatively small quantities per fruit) but for its extraordinary aromatic complexity. The rind contains volatile essential oils with a character unlike any other citrus: simultaneously lemon, mandarin, grapefruit, and something uniquely floral, spicy, and Japanese. Yuzu is used exclusively for its rind and juice rather than eaten as a table fruit. Applications: suimono garnish (a strip of zest cut into a leaf or pine-needle shape); ponzu sauce base; yuzu kosho fermented condiment; yuzubath (yuzuyu) where whole yuzu is floated in the bath on the winter solstice (Toji) for aromatherapy and warming; yuzu wagashi; yuzu sake; yuzu miso; and in modern pastry as a premier citrus aroma.

Intensely aromatic — simultaneously lemon, mandarin, floral, spicy, and something uniquely Japanese; the fragrance alone transforms a suimono from technically excellent to memorably beautiful
