I know nori and sesame seeds (sounds good!), but not your first ingredient. Over this-a-way, we use grapeseed oil drizzled on butter-free popcorn, and then we add a little fresh lemon juice as well. And top it off with Himalayan salt.
Kakimochi is also called arare—various small Japanese rice crackers.
