what is musubi
Aside from the spam, the only difference I see between them is the way it is put together. Musubi is a block of rice with a block of spam on top bind together with seaweed. Onigiri is put together a little differently because the meat is placed inside a ball of rice and then wrapped with a piece of seaweed.pam musubi is a popular treat in the American state of Hawaii, where it has become a bit of a cultural icon.
