[feast_advanced_jump_to]What is Mentaiko?
Mentaiko 明太子, the Japanese word preferred in the Fukuoka Prefecture, is a Japanese dish made of Alaskan pollock roe (cod roe). Raw mentaiko usually comes in sac membranes cured with salt, and other marinades like red chilli peppers and soy sauce.
Karashi Mentaiko (辛子明太子) is the Korean name for the Korean version dish of fermented pollock roe (myeongnan-jeot 명란젓). In 1949 during the Japanese occupation of Korea in World War II, Toshio Kawahara, founded the oldest mentaiko company called Aji no Mentaiko Fukuya" (ふくや).
He slightly modified myeongnan-jeot to suit Japanese tastes and introduced it as Karashi mentaiko. Tarako (鱈子) The milder, less spicy version in Japan.
Usually, mentaiko is a spicy cured pollack roe that is salty and savoury and never eaten in large amounts or as a main dish. It is served as a side dish with finely chopped green onions, sesame seeds and rice or as a filling in Onigiri rice balls.
Similar to tobiko (とびこ) is flying fish roe in Japanese cuisine, there are many different colors and flavors in mentaiko.
Some are spicy, some are yuzu flavored or just plain salted cod roe.
