Fukuoka is famous for its mentaiko—a spicy cod roe delicacy. For those of you wishing to buy some as souvenirs, sifting through the numerous options in the food hall can be overwhelming. But since I enjoy a kick to my taste buds, the decision was easy: mentaiko laced with wasabi!   Indulge yourself in this culinary delight by generously topping your rice with it. Just as spring onions pair nicely with the mentaiko, the spicy wasabi harmonizes with the umami-boosting cod roe. It's a feast for the palate as much as it is for the eyes. Revel in its lip-smacking savory taste. Your discerning taste buds will thank you for delighting them with such nuanced flavors.
