Mentaiko Spicy Cod Roe Fukuoka Korean Karashi

Fukuoka, Kyushu; post-WWII Korean immigrant adaptation; Fukuya company credited with commercialization in 1949

Mentaiko (spicy seasoned cod roe) is one of Japan's most beloved modern condiments, originating in post-war Fukuoka where Korean immigrants adapted the Korean spicy fish roe tradition (myeongran-jeot) into a Japanese product using suke (curing) with red pepper, sake, and various seasonings. The roe sacs of Alaska pollock (suketoudara) are cured and seasoned with red chili paste, mirin, sake, and kombu, creating a saline, spicy, umami-rich product. Plain tarako (unseasoned cod roe) exists alongside mentaiko, and both appear in a vast range of applications: tossed with hot pasta (tarako spaghetti, a flagship Japanese-Italian creation), as onigiri filling, squeezed onto hot potato, folded into butter for mentaiko toast, in mayonnaise sauces, and atop hot rice. The finest mentaiko from Fukuoka uses roe that is fresh and unburst, with each grain visible through the membrane. The balance between salt, spice, and the natural oceanic sweetness of the roe is the craft. Yamaguchi and Hokkaido also produce quality versions. Mentaiko has spawned an entire sub-cuisine of applications that have spread globally.
