This is so yummy and so simple. Last time I made this, I had some ground beef (mince) already cooked and in the freezer. I took that out in the morning to thaw, set the timer on the rice cooker and then only had one step to do when I got home.
Here's what you do.
500g beef mince
cooked rice (i like sushi rice best)
3 Tablespoons Sake
3 Tablespoons Mirin
3 Tablespoons Soy Sauce
All you do is cook the mince in a bit of oil, add the sake, mire and soy and continue to cook until the juice is gone. I did this on a med heat. Then you just stir that through the rice. You can shape it into onigiri (as shown below) or just eat it. Lately, we've opted to just eat it !!
And I add a little bit more soy sauce to my bowl ...
