You may want to double the recipe since it's so delicoius! It's a sweet and spicy dish cooked in thickened sauce.
One day when cooking seemed tedious, I threw together this simple dish over rice and it got rave reviews, so I recreated it and posted the recipe.
Since the flavor is strong, it is best eaten over rice. You can add the remaining sauce on top of the rice. Be careful not to serve too much!
Enjoy Japanese food around the world.
