Today, I’m going to be making, Nikumaki-Onigiri, beef wrapped rice ball.

We have so many varieties of rice balls, this is a high-end kind of onigiri.

Rich in taste and so satisfying, and easy to make!

If you don’t like fish in your Onigiri, this is the recipe you go for.

Serve as it is or cut in half.

I like to serve with Umeboshi.

Have a big bite of Sweet and savory riceball, and then take a little bite of Umaboshi.

These goes so well together.

You can use white rice as well.

I cooked rice with soy sauce, it tastes so much better than usual. 

Dried Shiitake mushroom and sesame seeds add a nice crunch and aroma.

It gives you power for the whole afternoon.

Give it a try and let me know how you like it!

    Do not squash too too hard but the rice should stick each other.


  • Spread a thinly sliced beef on a cutting board.
    Dust with all-purpose flour, and wrap rice ball.
    The flour sticks meat and rice when it cooked so that the rice ball would not fall apart.
    Heat your frying pan on medium, start cooking from seam side down.
    Rotate beef wrapped onigiri and cook all over the surface.
    Add in half a tablespoon of sugar, one tablespoon of mirin and soy sauce.

    Reduce the sauce until look shiny.
