Melted cheese with freshly cooked rice is delicious. The umeboshi, shiso, and bonito flakes go perfectly together.
I was chosen to be a Meiji Hokkaido Tokachi Camembert cooking tester, so I tried mixing it in rice balls.
The saltiness of umeboshi pickled plum varies from household to household. If you find the flavor lacking, adjust to your liking.
Enjoy Japanese food around the world.
