First there was butter in your coffee. But now, it appears that a pad on butter of your sushi is a thing.
Each piece of grilled freshwater eel sushi is composed of a small mound of sushi rice topped topped with a generous pat of butter with a small belt of nori to keep it in place.
RocketNews24 translated some of reviews of the sushi on social media: Diners say "it feels like it's melting in your mouth," and one enthusiastic fan wrote, "I could eat this every day!"
Butter and sushi seems like an odd pairing, but we won't be surprised if it starts appearing on other sushi restaurant menus soon.
