Kabu: Japanese Turnip, Its Varieties, and Its Place in Kyoto Cuisine
Origin
Japan — kabu cultivation documented from Nara period (8th century); Shogoin variety specifically developed in Kyoto over centuries of selective cultivation
Description
Kabu (Japanese turnip, Brassica rapa) holds a privileged position in Kyoto cuisine that is entirely disproportionate to its global reputation as a humble root vegetable — in the Kyoto culinary tradition, it is the raw material for senmaizuke (Kyoto's most refined pickle), a component of kabu-mushi (Kanazawa's ceremonial steamed dish), and a symbol of the winter shun that animates Kyoto's seasonal kitchen. Japanese turnip varieties are markedly different from European turnips in their delicacy: Kyoto varieties such as Shogoin kabu (a massive, spherical, pure-white variety grown in the Shogoin district of Kyoto), Manganji kabu, and Tenno kabu are all selected for sweetness, minimal bitterness, and exceptionally fine, smooth texture — the opposite of the peppery, sometimes woody character of European purple-top turnips. Shogoin kabu, which can grow to 2–3 kg while maintaining exceptional sweetness, is the raw material for Kyoto's iconic senmaizuke: the turnip is sliced ultra-thin (about 1mm) on a mandoline, arranged in a cedar barrel with salt, then seasoned with sweetened vinegar and strips of red yuzu peel in a process that requires several days to a week and results in a translucent, sweet-sour, delicately flavoured pickle with an elegant visual presentation of layered translucent slices. Beyond pickling, kabu in kaiseki appears as kabu no nimono (turnip simmered in light dashi until translucent and fragrant), in kabu-mushi (grated kabu-thickened steamed crab or white fish dish from Kanazawa), and in miso soup as a winter-season topping with its greens (kab no ha) used separately as a sautéed side vegetable.
