Onigiri with Uni

Onigiri, also known as omusubi or nigirimeshi, is a Japanese rice ball made from white rice. It is typically formed into triangular or cylindrical shapes and often wrapped in nori seaweed. While contemporary onigiri can feature a wide range of savory and sweet fillings, traditional versions frequently contain salty or sour ingredients like salted salmon or umeboshi. This easily portable food has been a staple as a hand-held meal or bento item since ancient times.
