Omusubi Mentaiko Mayo Onigiri
What it is
This is a pre-made rice ball, or onigiri, featuring a savory and slightly spicy filling. The core of the filling is mentaiko, which is salted pollock roe, blended with creamy mayonnaise. This combination creates a rich, umami-forward flavor profile with a subtle kick. The rice itself is typically seasoned and formed into a convenient, handheld shape, often triangular or cylindrical, making it a popular ready-to-eat snack or light meal.

This onigiri is designed to be eaten directly from its packaging. Simply unwrap it and enjoy. The mentaiko mayo filling is already incorporated into the rice ball. It can be consumed at room temperature or slightly chilled. For those who prefer a warmer bite, it can be gently heated, though care should be taken not to overheat the rice, which can alter its texture. It is a self-contained item ready for immediate consumption.
How it differs from similar foods
Unlike plain onigiri, this version offers a distinct flavor profile due to the mentaiko and mayonnaise. Mentaiko itself provides a unique salty and oceanic taste, while the mayonnaise adds a creamy richness that balances the roe's intensity. This makes it a more complex and satisfying option compared to simpler seasoned rice balls.
