Furikake is often brightly colored and flaky. It can have a slight fish or seafood flavoring, and is sometimes spicy. It can be used in Japanese cooking for pickling foods for onigiri, or rice balls.
Onigiri also known as omusubi or rice ball, is a Japanese food made from white rice formed into triangular or oval shapes and often wrapped in nori seaweed. Traditionally, an onigiri is filled with pickled ume, umeboshi, salted salmon, katsuobushi, kombu, tarako, or any other salty or sour ingredient as a natural preservative.
