Onigiri
Mild and slightly salty from the rice and seaweed, with flavor otherwise defined by the filling.
Lens analyzedOnigiri is a hand-shaped Japanese rice ball, often triangular, wrapped in a sheet of seaweed and filled with something savory like salted salmon, pickled plum, or seasoned tuna. It's a compact, portable snack or light meal, not meant to be reheated the way a hot dish would be.
Where it comes from
Onigiri has roots in Japanese travel food going back centuries, when rice balls provided an easy portable meal, and packaged versions became a convenience-store staple in Japan before spreading into North American Japanese and Asian grocery sections.
Buying it
Check that the seaweed wrapper is still crisp rather than soft or damp, and note the filling listed on the wrapper before buying. Triangular shapes with a separate plastic layer to keep the seaweed crisp until you unwrap it are a common design.
Storing it
Keep it refrigerated and eat it within about two days, since the rice firms up and loses its texture the longer it sits cold. Some brands recommend bringing it closer to room temperature before eating for the best texture.
Keeps about 2 days in the fridge.
