‹ Seasonal Ingredients

Description

Japan's indigenous citrus varieties constitute one of the world's most sophisticated small-citrus collections — each with distinct flavour, season, and culinary application. The principal varieties: Yuzu (the most famous internationally — intensely aromatic skin and juice used for flavouring, relatively little juice, peak winter): described as grapefruit crossed with lemon with a floral-herbal complexity; Kabosu (from Oita Prefecture — large, round, more juice than yuzu, more acidic, summer-autumn harvest): the primary ponzu citrus in Kyushu; Sudachi (from Tokushima Prefecture, Shikoku — small, very aromatic, extremely tart, summer-harvest): sliced thinly and squeezed over sanma (Pacific saury), matsutake, and other autumn dishes; Citrus junos vs Citrus sphaerocarpa vs Citrus sudachi — each uniquely Japanese; Daidai (bitter orange): used in traditional ponzu for its intense bitterness; Konatsu (Kochi Prefecture): mild, sweet-tart, eaten as fresh fruit.

The Thread

—Both Spanish Seville orange and Japanese yuzu/kabosu/daidai represent indigenous aromatic bitter/sour citrus used more for their aromatic compounds than their eating quality — both are primarily culinary-aromatic rather than eating citrus Spanish · (Catalan)
—Both Japanese sudachi/kabosu and Peruvian sour citrus represent highly acidic small citrus varieties that are used primarily to add vivid acid-aromatic intensity to dishes rather than as eating fruit Peruvian

Flavour Context

Yuzu: floral, herbal, perfumed — more aroma than acid; sudachi: very tart, bright green citrus with aromatic lift; kabosu: acidic, less aromatic than yuzu but more juice — each serves different culinary purposes
