I would recommend to wrap “mochi (rice cake)” in “nori (laver)” seaweed. It’s one of the nicest traditional cooking style. You might want to add a little bit of sugar to soy sauce, dip well-toasted cut pieces of mochi in that sauce and wrap the rice cake with nori. This is called “Isobe-maki”. You can adjust the proportion of soy sauce and sugar according to your taste.
